Can you search the twisted codebase to find out if they're using
platform.mac_ver()?  If yes, that's exactly the same problem I reported
here yesterday.  If not, it's almost certainly something similar.

Critical bit of the logs:

BTW, it would have helped if you had specified what "boom" means (i.e.
explained that you were getting an OS crash rather than a Python
traceback).  I was looking for this in particular, so it was easy to
find, but someone else might well have not bothered.

Ronald, I looked in gestaltmodule.c, and it's not doing a fork(), so it
must be buried in the Gestalt() call itself.  Which really makes this
Apple's bug unless Gestalt() is completely deprecated.  However, I don't
have enough Mac experience to make that certain.
