I am building a simulator for a parallel execution environment
and am considering using ISIS to manage message queues and perhaps
for distribution across processors.  I know that ISIS runs under
Mach, using Cthreads; my question is: does ISIS run on the BBN 
Butterfly, and if so can I get true parallelism between ISIS
lightweight tasks?  Otherwise, I'll have to run multiple ISIS processes
to get parallelism, and pay the overhead of message passing for
every interaction.
