It seems the correlation is that in 2.6, _ssl itself uses threads; in 
2.5 it did not, but in 3.1 it does and those same tests pass, as they do 
if _ssl.dll is not present in 2.6.

I don't know the cause but I did find an easy workaround:  Forcefully 
disabling threads in _ssl.c by adding #undef WITH_THREAD immediately 
after #include "Python.h" creates a _ssl.dll that allows the tests to 
pass.  While this may seem a bit crude, it's really the same situation 
that existed in 2.5, where the core is threaded and _ssl isn't thread-aware.

As for updating Cygwin's python to 2.6, I see that 2.5 is the default 
version in stable and up, with 2.6/3.1 available only in experimental. 
I suggest we do similarly; leave the distro default at 2.5.4 (rebuilt 
for 1.7) and add non-default (IOW nothing non-versioned in /usr/bin) 
python2.6 and python3.1 packages for users to try.
