Re: Did something change with respect to Emacs idle loop:

[Richard Stallman]

    Symptoms: Run processes like mplayer via start-process from
    inside emacs,  e.g. playing an mp3 file ---
    output comes to a stop after a fixed length of time -- typically
    about a minute. Any form of kbd activity --- even the first key
    in a multi-key sequence -- gets things unwedged i.e. the mp3
    stream continues to play.

Can you run Emacs under GDB and stop it at various times
to see where it is waiting?  Make a backtrace each time.

If you see a pattern in the backtraces, looking one way
while the subprocess is still going, and looking a different way
when it has stopped, that will give us a clue to start from.


Does anyone else observe this problem?
