The more I think about it, the more I think that std.concurrency isn't 
quite the right interface for cluster parallelism.  I'm thinking instead 
of doing something loosely based on, but not a translation of, 
boost::mpi.  The following differences between std.concurrency and what 
makes sense for MPI bother me:

1.  shared/immutable isn't needed when you're copying the data anyhow.

2.  spawn() is taken care of by the MPI runtime.

3.  std.concurrency doesn't support broadcasting.
