Absolutely.

I was agreeing with you, already. :-)
Given that Jon mentioned other, similar reports, involving other
libraries/extensions for python...I wonder if there's something in the
core of python (e.g. "how to build an extension DLL: this glue code will
be included in the xDLL automatically by pyDist::Builder [or whatever],
defining a custom DllMain()...") that's doing something windows-ish,
when it ought to be doing it unix-ish on cygwin.
E.g. I wonder if this is bigger than just Twisted, or just
openssl+python/Lib/thread [1,2] etc.
