hang on exit bug under Linux

ssh is a general purpose method of running remote commands as if they were
locally.  Not "specially written remote commands", not "custom apps".  Just
remote commands.

That's what it inherited from rsh, and though I perhaps use this
functionality a bit more...strenuously...then others, I think I have a
reasonable expectation for dozens of processes to not accumulate.

I shouldn't have to rewrite applications, or even have to investigate how
they function in order to run them.  For the most part, ssh is excellent
about this.  Every once in a while though...and of course, that's the
problem.  Nothing worse than intermittent failures.
