[Pyrex] pyrex and GIL

[Simon Burton]

Hi all,
I'm using a "cdef" function as a callback routine for a library
that calls from a different thread.
The callback uses a PyEval_AcquireThread/PyEval_ReleaseThread pair.
So far I've got it to work, sort of.

I'm running into problems to do with exception handling*. It would be nice
to have exceptions work so I can see what's going wrong in the callback.
A try/except doesn't catch anything. The offending call is to a numarray routine.

I may need to have PyEval_ReleaseThread called after
all pyrex's clean up stuff, which is supposed to be called with the GIL held.

Any suggestions/workarounds?

Simon.
