I can't say how useful it is generally because Emacs 22 is still stuck in CVS.
From personal use, however, I've sometimes found watchpoints deleting
themselves to be a nuisance. Sometimes I've got around by specifying an adress
rather than a variable name.

Would this be straightforward to implement? Isn't there anything in their
nature that makes this easier to do for watchpoints?
