I hadn't noticed it.  The ESCDELAY timeout is one second, which does
seem long.  Recently I've been testing some application code which
uses the ESC key, and just to get things done had reset ESCDELAY to 50
(milliseconds).  But the times I've been seeing are consistent, and I
didn't see any problems with typing ESC more than once.
