d4ceb31664 Bump the magic number to avoid sharing bytecode between 2.3 and 2.4.
Revise the long comment that explained details of the magic number
in gory detail.

ff5bc50bb0 Improve byte coding for multiple assignments.
Gives 30% speedup on "a,b=1,2" and 25% on "a,b,c=1,2,3".

1515fc2a01 A 2% speed improvement with gcc on low-endian machines. My guess is that this
new pattern for NEXTARG() is detected and optimized as a single (*short)
loading.

fba1cfc49a LIST_APPEND is predicably followed by JUMP_ABSOLUTE.
Reduces loop overhead by an additional 10%.

2d783e9b16 Move the code for BREAK and CONTINUE_LOOP to be near FOR_ITER.
Makes it more likely that all loop operations are in the cache
at the same time.

db0de9e7ca Speedup for-loops by inlining PyIter_Next(). Saves duplicate tests
and a function call resulting in a 15% reduction of total loop overhead
(as measured by timeit.Timer('pass')).

f114a3ae63 Refactor and optimize code for UNPACK_SEQUENCE.
* 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.

dd80f76265 SF patch #910929: Optimize list comprehensions
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.

30e97dbe96 SF Patch #902444: Use process scope thread on FreeBSD. System scope
is too expensive on FreeBSD's KSE threading infrastructure and
even test_threadedimport fails on default setting.

786ea6bc23 Add pystack definition to Misc/gdbinit with some explanation of its behavior
and add flag comments to ceval.c and main.c alerting people to the coupling
between pystack and the layout of those files.

ecfeb7f095 This is my patch #876198 plus a NEWS entry and a header frob.
Remove the ability to use (from C) arbitrary objects supporting the
read buffer interface as the co_code member of code objects.

a72169871d SF patch #884022: dynamic execution profiling vs opcode prediction
(Contributed by Andrew I MacIntyre.)

disables opcode prediction when dynamic execution
profiling is in effect, so the profiling counters at
the top of the main interpreter loop in eval_frame()
are updated for each opcode.
