  7296 100634 vlc      48.521557 RET   sigwait 4
  7296 100634 vlc      48.521577 PSIG  SIGCHLD caught handler=0x804254220 
mask=0x5007 code=CLD_EXITED
  7296 100634 vlc      48.521631 CALL  write(0xa,0x804354922,0x1)

It seems that sigwait() returns EINTR, which is not even a specified error for 
sigwait(). What is worst, SIGCHLD is blocked on the calling task.

This is completely bogus behaviour from the run-time as far as I can tell.

Best regards,
