> Currently the event loop has two wait conditions, one a condition variable and the other I/O ({{epoll}} or equivalent). As far as I can tell the conditiona variable is useful only during start up when the I/O wait data is not yet available. The event loop should be changed to wait on one or the other but not both as this can create artificial latency when an event breaks one wait condition but not both.
