Yes.  The idea is that 'ssh-agent command' should be more-or-less equivalent to 
running 'command', with ssh-agent running as a subprocess.

The ssh-agent subprocess periodically checks to see if its parent is still 
alive, and it exits when the parent has died.  Someone should figure out why 
this is not working on Cygwin.
