If the 'e' packet is going to change gdb's behavior while debugging
threads, this needs to be discussed and considered.  It may amount to
a bug in the specification of the 'e' packet.

And in fact, given the behavior that you describe in your first message, 
the 'e' packet _is_ going to change gdb's behavior while debugging
threads.
