This is a followup bug report to fix wrong implementation of
_PyGILState_Reinit() introduced by http://bugs.python.org/issue10517.
I don't have a standalone test case yet. Problem occurs under mod_wsgi with
Python 2.7.2 and thus

Note that this doesn't apply to default: the problem is that 2.7 and 3.2 don't
use native TLS, and with the ad-hoc TLS implementation, a NULL value isn't
supported:

So, the documentation you quote is only to do with the main

You're right, my bad.

So the solution would be simply to backout this patch on 2.7 and 3.2.
Actually, I just checked, and the native TLS implementation is present in 3.2,
so this problem shouldn't show up: did you test it with 3.2?
AFAICT, this should

True. Doesn't appear to be an issue with Python 3.2.2. Only Python 2.7.2.
I was not aware that the TLS mechanism was changed in Python 3.X so assumed
would also affect it.
So, looks like the change shouldn't have been applied to
