* Defer error handling for wrong number of arguments to the
  unpack_iterable() function.  Cuts the code size almost in half.

* Replace function calls to PyList_Size() and PyTuple_Size() with
  their smaller and faster macro counterparts.

* Move the constant structure references outside of the inner loops.

Side-effects were deemed unnecessary and were causing problems at shutdown
time when threads were catching exceptions at start time and then triggering
exceptions trying to call currentThread() after gc'ed.  Masked the initial
exception which was deemed bad.

longer needed.

The writelines() method now accepts any iterable argument and writes
the lines one at a time rather than using ''.join(lines) followed by
a single write.  Results in considerable memory savings and makes the
method suitable for use with generator expressions.

and list.extend().  Factoring the inner loops to remove the constant
structure references and fixed offsets gives speedups ranging from
20% to 30%.

the code by grouping common cases together.

* Using addition instead of substraction on array indices allows the
  compiler to use a fast addressing mode.  Saves about 10%.

* Using PyTuple_GET_ITEM and PyList_SET_ITEM is about 7% faster than
  PySequenceFast_GET_ITEM which has to make a list check on every pass.

Since it is known ahead of time that UTC and GMT always have no DST adjustment
then just set the isdst value to 0 even if tzname[0] == tzname[1] .
Fixes bug #897817 .

Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.

(Championed by Bob Ippolito.)

The update() method for mappings now accepts all the same argument forms
as the dict() constructor.  This includes item lists and/or keyword
arguments.

is too expensive on FreeBSD's KSE threading infrastructure and

This can break possible code (datetime module needed changing, for instance)
that uses 0 for values that need to be greater 1 or greater (month, day, and
day of year).

Simplifies the API, reduces the code size, adds flexibility, and makes
deques work with bisect.bisect(), random.shuffle(), and random.sample().

and add flag comments to ceval.c and main.c alerting people to the coupling
between pystack and the layout of those files.

* Add doctests for the examples in the library reference.
* Add two methods, left() and right(), modeled after deques in C++ STL.
* Apply the new method to asynchat.py.
* Add comparison operators to make deques more substitutable for lists.
* Replace the LookupErrors with IndexErrors to more closely match lists.
