omniORBpy has to do exactly this. When I first wrote it, I created a
new Python thread state on every call, but I discovered that that
imposes a huge overhead. I implemented a cache of thread states, which
halved the invocation time.

The code is in C++, but reading it might help you figure out something
useful to you. Look at pyThreadCache.h and pyThreadCache.cc in this
CVS directory:

Cheers,

Duncan.
