MPI and python+threads on IRIX

Hi,
I'm trying to add a dynamic module using MPI on a 2.3.4 Python
with threads (posix).
The interpreter blocks into the dlopen (dynload_shlib.c) if any
reference to the IRIX libmpi.so (actually SGI/IRIX 6.5) appears.
The docs say that the use of MPI+dlopen requires a call to MPI_Init_thread
before the dlopen. I wonder how I can build a shared module using
mpi if it blocks inside the dlopen ! It looks like the dlopen itself
blocks at the time it reads the libmpi.so (is it possible).

The MPI modules I've found are not ported on SGI (yes I know...)

Any hints ? Help ? Piece of advice ? Idea ? Patch ? Coconut ?
