Shorter term than you may think :)  My plan now is something like this:
  - Cleanup patches, as posted
  - Internal support for multiple locations per breakpoint
  - Adapt watchpoints to use the multiple locations support, which will
    be rather cleaner than what we have now.
  - Then move on to fun stuff with breakpoints.

Could you give me a pointer to the watchpoint changes you're talking
about?  I don't recall them.

That's the concept, but I don't think we have a real problem with
continuing to overload breakpoint for that.  Consider "info break".
