Hi!
Isn't this thread unsafe?

pthread_mutex_t event_mutex[1];

int SharedMemoryBase::eventPost(event_t* event)

++event->event_count;

}
Should not event_count use a std::atomic?
Or is SharedMemoryBase::eventPost expected to not be thread safe to be
called concurrently?
It's always called with shared memory mutex taken, i.e. no concurrency
problems.
