For yet another time: This is *totally* flawed.

You ***CANNOT*** know which thread will receive the SIGCHLD signal. It 
could be the sigwait thread, it *might* by chance be the Qt4 thread, or 
it could be any other thread that would not block SIGCHLD.

As such if your code need to receive a signal, it is simply PLAIN 
BROKEN. There are only two exceptions:
1/ if the signal is emitted with pthread_kill() - not applicable here.
2/ single thread per process - if your library needs this, then you 
cannot use it in VLC at all.

Please revert.
