I *really* find that hard to believe.  I've run cygwin on some pretty
slow computers and I've never noticed a slowdown from running bash
in a command shell.  Even Windows should be smart enough to know that
it can swap out most of command.com when bash.exe is running so I
don't know how this could be a resource thing.
