7df5e7f4b2 Patch 1145039. 
set_exc_info(), reset_exc_info():  By exploiting the
likely (who knows?) invariant that when an exception's
`type` is NULL, its `value` and `traceback` are also NULL,
save some cycles in heavily-executed code.

This is a "a kronar saved is a kronar earned" patch:  the
speedup isn't reliably measurable, but it obviously does
reduce the operation count in the normal (no exception
raised) path through PyEval_EvalFrameEx().

The tim-exc_sanity branch tries to push this harder, but
is still blowing up (at least in part due to pre-existing
subtle bugs that appear to have no other visible
consequences!).

Not a bugfix candidate.

5132407868 Added limits to the replace code so it does not count all of the matching

c5da53ba78 substring split now uses /F's fast string matching algorithm. 
(If compiled without FAST search support, changed the pre-memcmp test
   to check the last character as well as the first.  This gave a 25%
   speedup for my test case.)

Rewrote the split algorithms so they stop when maxsplit gets to 0.
Previously they did a string match first then checked if the maxsplit
was reached.  The new way prevents a needless string search.

f4ef11659c Need for speed: Patch #921466 : sys.path_importer_cache is now used to cache valid and 
invalid file paths for the built-in import machinery which leads to
  fewer open calls on startup.

  Also fix issue with PEP 302 style import hooks which lead to more open()
  calls than necessary.

02494764cb Explicitly close files. I'm trying to stop the frequent spurious test_tarfile 
failures on Windows buildbots, but it's hard to know how since the regrtest
failure output is useless here, and it never fails when a buildbot slave runs
test_tarfile the second time in verbose mode.
