Hmmm... "delete global"... you're right - I use globals so
infrequently that it wouldn't have occurred to me that I would have to
delete something that didn't exist. That's pretty screwy, IMO. I don't
think there's anything else in xtalk that acts that way. Constants
certainly don't. If the compiler enforced reference counting when
compiling that would take care of this.

Yet another reason to avoid the Dreaded Global.
