Well, I invite you to read again my e-mails and if it is not clear, have
a look at the code (src/video_output/vout_intf.c:vout_Snapshot and
src/control/mediacontrol_audio_video.c:mediacontrol_snapshot) to better
understand what I am talking about.

More seriously, I perfectly understand that the existing code is not
entirely correct and has the potential to create hard-to-find deadlocks
and non-understandable behaviour, even though in its actual usage it
currently works (do not bother to reply "appears to work but is
unbearably broken", I know that). I will fix that.

Some suggestions :
- the vlc_object_wait doc should mention this spurious wakeup problem
- btw, it currently says that the function "@return true if the object
is dying and should terminate.", while the return type is void.

Thanks for your help.
