Since the fast_yield branch target was introduced, it appears that most
...
tests of "why" against WHY_YIELD became useless. This patch removes them,
but assert()s that why != WHY_YIELD everywhere such a test was removed.
The test suite ran fine under a debug build (i.e., the asserts never
triggered).

new pattern for NEXTARG() is detected and optimized as a single (*short)
loading.

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.

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.

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.

Add PyThreadState_SetAsyncExc(long, PyObject *).

A new API (only accessible from C) to interrupt a thread by sending it
an exception. This is not always effective, but might help some people.
Requested by Just van Rossum and Alex Martelli. It is intentional
that you have to write your own C extension to call it from Python.
Docs will have to wait.
