The first three are already in (except I'm a little fuzzy
about the state of MI).  Oh, and by the way (Eli and Joel),
I owe you a NEWS entry.

The fourth (process record/replay) is what's currently on the table
for discussion.

The fifth bullet item (reverse exec from external sources such as
VMware, Virtutech etc). doesn't require any approval or action on
the part of the gdb maintainers, unless it uncovers a bug or problem
in the gdb parts.  Y'all (including me) can just go to town!  ;-)
