Hello! :)

True also for MPICH 1.0.10 on DEC Alpha WS. If you forget to call 
MPI_Finalize before you exit(), on each machine involved a process remains,
creating a load of 1. Not exactly what your Sysadmin will like ... ;-))

I am very interested in these modules for Modula II, and Oberon. Can you
give some more information about the completeness of your project? Are
there preliminary releases available?
