Help for local repository usage

[Chris Muller]

You should be able to use multiple sessions to the same repository in
one image.  They each see their own copy of the persistent model, so
don't let the copies reference each other.   Since Magma session
employs its 'guard' on practically everything, it should be ok for
multiple Processes to use one session.

These kinds of bugs can be hard to track down.  Are you only doing
commit: [] within each process or are #begin sends in separate places
in the code from #commit?  Can you simplify down to one Process per
session?  Just 4 processes, 4 sessions?
