[MPlayer-dev-eng] [HACK] make nohup mplayer/mencoder work

[Reimar Döffinger]

Hello,
it is quite a hack particularly since it introduces a race condition
(though strictly speaking one exists already in nohup.c anyway, so it
matter little IMO, which is also the reason I did the check this way).
Still, it makes nohup work with mencoder/mplayer so it might be worth it
anyway...

Greetings,
Reimar Döffinger
