I know python can do this because mod_python uses this
feature.

Also, this may be completely irrelevant, but I had problems
connecting a callback in a C extension to python. I was
hooking up a MIDI keyboard to python. I could play notes
just fine from python to the keyboard, but when I tried to
go the other way (hitting a key on the keyboard), it
triggered a callback into my extension module, and that
screwed up the python interpreter.

The solution had something to do with the python interpreter
lock. I forget how it worked. I stole the code from someone
else. But if it helps, the code is online at:
