How to prevent a stack from loading twice (in Linux)

[Peter Alcibiades]

Ken, the problem is, they can start a second copy of the app when one copy of
it is already running.  But the stack script contains the following:

on reloadStack
close this stack
end reloadStack

So should not that cause it to check and see if it is already running, and
if so quit?  I also have tried with just

on reloadStack
end reloadStack

But the second copy loads in either case.

What I want to happen is that if someone tries to start the app when it is
already running, for it to fail and not start.  Maybe give an error message,
but that's not essential.
