Sounds like the Amiga's OS to me.  And UNIX doesn't do this?
I'm trying to be a UNIX nut in training, but I keep hearing about
these new tricks that seem to be rather hard to teach the
old dog.  I'd hate to wake up in 5 years and realize that UNIX
had become to workstations what MS-DOS is to PCs now.  Somebody
pinch me.
