I haven't looked at how hard it'd be, but it seems to me that it'd
be a good idea for gdb to note that a shlib event has happened without
immediately doing anything about it.  Then, when the target stops
for some other reason (than a shlib event), we handle all of them at
once.  This should cut down on the memory traffic greatly.
