I think Carl is using Linux, so the awful overhead of process creation
in Windows doesn't apply.  Forking in Linux isn't that big a deal.
os.system() usually forks a shell, and the shell forks the actual
command, but even two forks per ssh is no big deal.  The Apache web
server usually runs with a few hundred processes, etc.  Carl, just how
many of these ssh's do you need active at once?  If it's a few hundred
or less, I just wouldn't worry about these optimizations you're asking
about.
