PROTON-1496: epoll proactor - improved timers implementation with single timerfd kernel resource
> C epoll proactor needs better timer implementation for connections
> ------------------------------------------------------------------
>
> Key: PROTON-1496
> URL: https://issues.apache.org/jira/browse/PROTON-1496
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Affects Versions: proton-c-0.18.0
> Environment: Linux environments with epoll support
> Reporter: Clifford Jansen
> Assignee: Clifford Jansen
> Priority: Major
>
> The epoll proactor allocates a timerfd per connection. This is a convenience for the initial implementation and may surprise some applications running into system limits on file descriptors twice as fast as expected.
> The timer is used for heartbeats. It should be possible to write a per-proactor heartbeat timer that is shared among the connections
