Sorry it took so long to reply Pierre; I was really hoping someone
else (like Lijun) would answer.

Anyway, I don't have an implementation of multithreading support, at
least not yet.

THe best way to safely unblock threads that I know of is to write a
thin wrapper around your function which uses Py_BEGIN_ALLOW_THREADS
and Py_END_ALLOW_THREADS around a call to the real function.
