I *used* to do that, back with gm-1.0.X. It has not been necessary since,
except for an early 1.2.X which was unusually buggy. I suspect most of the
rumors about that are stale, since people seem to think I'm still doing that
on the FSL system.

Now "cleaning up ports" is an ambiguous problem. It could be the case that
these folks are having a problem getting all their MPI or other
myrinet-using processes to exit. The next program to come along will then
complain that the port is in use. In that case, one way to "clean up ports"
is to reload GM, but I prefer using a script which parses the output of
gm_board_info and kills the guilty processes.

Of course, other people can shed more light on their problems...
