Leif Hedstrom commented on TS-4260:
-----------------------------------
It might be worthwhile to revisit the time wheel event loop changes as well
with this?
> Change event loop to always stall on waiting for I/O.

> 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.
