I wonder whether it is the right thing on the gdb side.
Right now we have the rule that linespecs for breakpoints apply to all
inferiors; but this rule isn't followed for catchpoints.
I tend to think it ought to be, for consistency and simplicity; followed
up by using it{etc}sets for filtering out uninteresting events.
I don't want to derail this patch though.
And arguably it is ok for gdb to present one thing to the user but more
useful for gdbserver to present a different view to gdb.
Tom
