bug#10580: 24.0.92; gdb initialization takes more than one minute at 100% CPU

[Dov Grobgeld]

I finally ran emacs-24 under debugger to figure out where it got
stuck. What I found was that it is stuck in keyboard.c where in
read_key_sequence() the control keeps jumping back to the
replay_sequence label. Does this ring a bell to someone?

Regards,
Dov
