Shouldn't this be under "info" or "show"?

I think that if you made this accept a regex, it'll
end up being much more useful. Particularly, to filter
the extra info fields. Another interesting filter
could be: threads stopped in "foo_regex" function,
or address.

But still, the user will still have to manually pick
the output of the previous command. I think it'd even
be better if the command had a switch that created a
thread group (itset or thread set, whatever) from the threads
that matched. Only problem is we don't have thread
sets support, yet.
