Mikolaj Golub 1c1310eed7 Use cv_broadcast() instead of cv_signal() when waking up threads ... waiting on an empty queue as the queue may have several consumers. Before the fix the following scenario was possible: 2 threads are waiting on empty queue, 2 threads are inserting simultaneously. The first inserting thread detects that the queue is empty and is going to send the signal, but before it sends the second thread inserts too. When the first sends the signal only one of the waiting threads receive it while the other one may wait forever. The scenario above is is believed to be the cause of the observed cases, when ggate_recv_thread() was getting stuck on taking free request, while the free queue was not empty.
