I have not have the time to analyse this in more detail, but from first glance I
tend to say that the lock aquired in line 1058 of event.c is being held for too
long, such that we can run into a deadlock. In the backtrace below thread 2 is
holding this lock and preventing all the worker threads from doing their jobs
(they need to get hold of this lock). OTH thread 2 waits for a free worker via a
conditional wait. BOOOM.
