I haven't had a chance to look at the other patch, but, yeah,
it does feel like a hack! :-/.

But I'm sympathetic to the issue - it's tough to have to wait
an extra 20secs when you know that you don't have any breakpoint
refering to any SO... My thoughts on this: Perhaps a setting
in the "maintenance set/show" that the user could change to deactivate
breakpoint reset.  The default is the current behavior, but if the user
knows what he's doing, he can change it. Not sure what the other
maintainers think about that. Horrible, but better than nothing.

That being said, I still think we should try to do as good a job
as we can automatically, so your first suggestion should also be
incorporated.
