[Python-Dev] test_re failures, Windows, 2.3 maint

I sent test_re output from Windows on 2.3 maint yesterday. Two tests fail
with "maximum recursion limit exceeded".
Why do we expect them not to fail?
32-bit Windows may be unique in using this check:
if (level % 10 == 0 && PyOS_CheckStack())
PyOS_CheckStack() there isn't guessing, it's using Windows-specific
facilities to check directly whether the C stack is about to overflow.
In test_bug_418626, that check triggers twice, once at level = 15090 and
again at level 15210.
In test_stack_overflow, it triggers once at level 15210.
The test comments appear to believe that sre shouldn't be recursing at all
in these tests, but 15K+ levels is hard to sell as no recursion <wink>.
