It seems worth noting that xterms showing login shells on non-MacOS X
hosts do not disappear when I background a non-existent command. But
both eterm and xterm on OS X do disappear, regardless of whether I
spawn the xterm from the menu of X11.app or by typing
xterm -e ssh localhost
in another xterm.
Appears to be a bug in Mac OS X's tcsh and csh implementations, as it
doesn't happen with sh?

That should only be the case if the X window, was started with a

Running as a subshell: (asdfasdf &)
or
tcsh -c asdfasdf &
will cause less problem.
Can you explain this in a bit more detail? The behavior is
counter-intuitive, and not duplicated in other shells (in the 'sh'
family tree).
Why would a login shell exit if an attempt to launch an application in
the background failed because the app wasn't found?
In any case, if accurate, this is the answer we've been seeking, lo
these many moons...
Also the AppleTerminal has different characteristics.
We've noticed this.
Cheers,
Justin
