+ Took the "list" argument out of the other functions that no longer need
it.  This speeds things up a little more.

+ Small comment changes in accord with that.

+ Exploited the now-safe ability to cache values in the partitioning loop.
Makes no timing difference on my flavor of Pentium, but this machine ran out
of registers 12 iterations ago.  It should yield a small speedup on a RISC
machine, and not hurt in any case.

instead of testing whether the list changed size after each
comparison, temporarily set the type of the list to an immutable list
type.  This should allow continued use of the list for legitimate
purposes but disallows all operations that can change it in any way.
(Changes to the internals of list items are not caught, of cause;
that's not possible to detect, and it's not necessary to protect the
sort code, either.)

credit for complaining about this and for testing these changes.

RegistryQueryValue requires that its fourth argument be initialized to
the length of the buffer being passed in, this wasn't being done.  I
also split the call and status test into two lines with a local variable
so that I could look at the status in the debugger.

Added raw strings, imaginary literals, assert and exec (!) keywords, a
table about Resererved classes of identifiers, and more.

# checkin email because my PC doesn't have the "Mail" command.

Add threading (now that it works).  Also some small adaptations to
Unix again.

Add a clarifying comment about the new ENTER_OVERLAP and
LEAVE_OVERLAP_TCL macros; get rid of all the bogus tests for deleted
interpreters (Tcl already tests for this; they were left over from an
earlier misguided attempt to fix the threading).

doesn't depend on the value of os.sep.  (I.e. ported to Windows :-)

There were some serious problem with the thread-safety code.
The basic problem was that often the result was gotten out of
the Tcl interpreter object after releasing the Tcl lock.
Of course, another thread might have changed the return value
already, and this was indeed happening.  (Amazing what trying
it on a different thread implementation does!)

The solution is to grab the Python lock without releasing the
Tcl lock, so it's safe to create a string object or set the
exceptions from the Tcl interpreter.  Once that's done, the
Tcl lock is released.

Note that it's now legal to acquire the Python lock while the
the Tcl lock is held; but the reverse is not true: the Python
lock must be released before the Tcl lock is acquired.  This
in order to avoid deadlines.  Fortunately, there don't seem to
be any problems with this.

(The "sort of" is because it uses kbhit() to detect that the user
starts typing, and then no events are processed until they hit
return.)

Also fixed a nasty locking bug: EventHook() is called without the Tcl
lock set, so it can't use the ENTER_PYTHON and LEAVE_PYTHON macros,
which manipulate both the Python and the Tcl lock.  I now only acquire
and release the Python lock.

(Haven't tested this on Unix yet...)

there are no more completions left.  (This for compatibility with
Donald Beaudry's code.)

Unix!

the tty and the caller can deal with the interrupt.

In the windows version, recognize ^C and raise KeyboardInterrupt (not
sure if this is needed, but can't hurt).

This second problem only shows up if LDLAST is not an empty string (such
as with threads enabled on DEC Alphas).

The first one only shows up if $prefix != $exec_prefix, and the problem
is caused by the recent change in location for config.h.

the outcome of the test for max has changed.

should only be set to application/x-www-form-urlencoded when the
method is POST.  E.g. for PUT, an empty default (defaulting to
text/plain later) makes more sense.

Also implement __setitem__(), more-or-less correctly (GvR).

- explain seekable
- when seekable==1, test fp.tell() and set it to 0 if that fails
- support overridable method iscomment(line) to weed out comments
- check for unread() method on file object before trying to seek

And one of my own:

- Add a get() method which behaves like a dictionary's get(); this is
actually implemented by giving getheader() an optional second argument
to specify the default, and aliasing get to getheader.
