Re: [Python-Dev] Cygwin: Problem detecting subprocess termination after _spawn_posix in distutils?

Sorry, it was _spawn_posix I extracted (and have instrumented in the live version) - I have no idea where "_spawn_all" came from. I am indeed running under Cygwin Python.

Here-s a diff -u output against the original spawn.py so you can see what I have changed.

The only environment variables that don't appear in the shell output from the env command are INFOPATH, MAKE_MODE and PLAT. I am still flummoxed.
