value, based on comments from Tim Peters.

We occasionally received reports from people getting "invalid tstate"
crashes (this is a fatal error in PyThreadState_Delete()).  Finally
several people were able to reproduce it reliably and Tim Peters
discovered that there is a race condition when multiple threads are
calling this function without holding the global interpreter lock (the
function may be called without holding that).

Solved the race condition by adding a lock around the mutating uses of
interp->tstate_head.  Tim and Jonathan Giddy have run tests that make
it likely that this fixes the crashes -- although Tim hasn't heard
from the person who reported the original problem.

seem to be living there.

always lowercasing the option name, call a method optionxform() which
can be overridden.  Also make the regexps SECTRE and OPTRE non-private
variables so they can also be overridden.

Edited several of the descriptions for English usage and more
consistent style.

	 mode attribute of the file object (if it has one), otherwise

ExtensionClasses in isinstance() and issubclass().

  - abstract instance and class protocols are used *only* in those
    cases that would generate errors before the patch.  That is, there's
    no penalty for the normal case.

  - instance protocol: an object smells like an instance if it
    has a __class__ attribute that smells like a class.

  - class protocol: an object smells like a class if it has a
    __bases__ attribute that is a tuple with elements that
    smell like classes (although not all elements may actually get
    sniffed ;).

confusing to end users of IDEs.

Added support for unseekable files.

(I use unqualified excepts since we don't know why the seek/tell might
fail.  In my case it was because of an AttributeError.)

only by the interpreter core and is not overridable by objects.

Based on comment from David Ascher on the list.

Problem: rfc822.py in 1.5.2 final loses the quotes around
quoted local-part names.

The fix is to preserve the quotes around a local-part
name in an address.

Test:

	import rfc822
	a = rfc822.AddrlistClass('(Comment stuff) "Quoted
name"@somewhere.com')
	a.getaddrlist()

The correct result is:

	[('Comment stuff', '"Quoted name"@somewhere.com')]

Noted that name=value is allowed in addition to name: value.

Also added a short circuit for the regression test suite since CVS
insisted on putting this file in the main branch. :(

- Don't call Py_FatalError() when initialization fails.

- Fix bogus use of return value from PyRun_String().

- Fix misc. compiler errors on some platforms.
