Did something change with respect to Emacs idle loop:

[T. V. Raman]

Following up to my own message:
I can now confirm that the behavior I describe is due to some
change in Emacs since Sunday.

I did a cvs update -D 2006-09-17 built the result, and the
strange behavior I described with respect to both mplayer and
emms has now gone, things are back as they should be.

Additional details:

This is a desktop system, and it's running powernowd --- though
in the ceasing  up of mp3 streams I describe below, things dont
get unwedged when you have keyboard activity on another console,
so it's not that the entire machine has gone to sleep -- just
Emacs.

So anyway, I believe the bits that changed the behavior got
checked in  since Sep 17, and sometime before Tuesday September
19 -- I started noticing the bizarre behavior first yesterday
evening PDT
