           Summary: [PATCH] unblocking blocked pad does not release all
                    blocked threads
           Product: GStreamer
           Version: 0.10.10
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)
        AssignedTo: gstreamer-bugs at lists.sourceforge.net
        ReportedBy: manauw at skynet.be

     GNOME version: Unspecified
   GNOME milestone: Unspecified


GST_PAD_BLOCK_SIGNAL only wakes up a single thread waiting on a blocked pad.
However, it is possible to have more than 1 thread blocked, e.g. in the
situation
elementX ! queue:
- elementX sends event, is queued, queue_loop tries to send out and blocks src
- elementX (after sending event) performs pad_alloc, this thread crosses the
"queue thread boundary" and is also blocked on queue.src
