David Bolen added the comment:
I ran a few more tests, and the generated executable hangs in both release and
debug builds. The closest I can get at the moment is that it's stuck importing
errno from the "import sys, errno" line in os.py - at least no matter how long
I wait after starting a process before breaking out, output with -v looks like:
> python_d -v
# installing zipimport hook
import zipimport # builtin
# installed zipimport hook
# D:\cygwin\home\db3l\test\python2.7\lib\site.pyc matches
D:\cygwin\home\db3l\test\python2.7\lib\site.py
import site # precompiled from D:\cygwin\home\db3l\test\python2.7\lib\site.pyc
# D:\cygwin\home\db3l\test\python2.7\lib\os.pyc matches
D:\cygwin\home\db3l\test\python2.7\lib\os.py
import os # precompiled from D:\cygwin\home\db3l\test\python2.7\lib\os.pyc
import errno # builtin

I never have a problem interrupting the process, so KeyboardInterrupt is
processed normally - it just looks like it gets stuck in an infinite loop
during startup.
