bug#16505: Acknowledgement (24.3.50; Emacs seems to loose key events when typing fast (seriously))

[Anders Lindgren]

Got it! It's revision 110793 -- this is a change to nsterm.m (hence an OS X-specific problem).

The bzr log is as follows:

revno: 110793

fixes bug: http://debbugs.gnu.org/8680

author: Michael Marchionna <tralfaz@pacbell.net>

committer: Chong Yidong <cyd@gnu.org>

branch nick: trunk

timestamp: Sun 2012-11-04 11:34:10 +0800

message:

  * nsterm.m: Add NSClearLineFunctionKey and keypad keys.

  (keyDown): Remap keypad keys to X11 virtual key codes.

When looking at the code, it's unfortunately not obvious (to me) what the cause is...

If that is the range, the only relevant commit seems to be 110802.

Try reverting only 110802.
