Dunno.  Maybe we've read it over in HPDF's parallel debugger's "standard",
or a PR or something.  Maybe Frysk implemented it?  It's certainly not
a novel idea.  ;-)

Anyway, that handles the symbol scoping, not the fact that to set
a watchpoint, the frame where the local is defined needs to be 
active, otherwise, you can't read the initial value for
comparision and change detection.  Certainly more would have
to be changed to make it work.

I certainly think that the feature is quite useful even
with the locals caveat.
