Bug#723914: mplayer: 100% CPU spin after laptop suspend/resume

[Paul LeoNerd Evans]

Package: mplayer
Version: 2:1.0~rc4.dfsg1+svn34540-1+b2
Severity: normal

I use mplayer to pull an icecast stream from my mpd server to my
laptop, using

  mplayer -playlist http://SERVER:8000/mpd.mp3.m3u 

If I forget to SIGINT the mplayer when I suspend my laptop, then on
resume it enters a 100% CPU spin and does nothing. An strace on both
parent and child mplayer process at this point shows no syscalls at all
(so it's a pure CPU spin).

It does respond to SIGINT, but requires two signals to quit it; the
terminal scrollback looks like:

  Cache empty, consider increasing -cache and/or -cache-min. [performance issue]
  A:15894.3 ( 4:24:54.3) of 0.0 (unknown)  1.8% 0%
