[PATCH v5 0/5] MR1278: winegstreamer: Do not destroy condition variables when a thread is waiting on them.

[Giovanni Mascellani (＠giomasce)]

It is possible that a stream is destroyed while another thread is waiting on
event_empty_cond or event_cond. The waiting thread should have the opportunity
to be rescheduled and exit the critical section before the condition variables
and the mutex are destroyed.
