Yes, moving to poll() (and alternatives) is a TODO list item.
We're been moving slow because of a few unknowns, namely
interaction with threads and performance. Positive operational
experience using poll() here would help move things forward.
poll tends to suffer from thousands of connections. But the move to epoll would
be an a bit larger patch. There you can not loop over all fd's and see if any
of those is readable or writable, epoll gives you the descriptors on which
something has happened. To support huge numbers of connections where 99% of
them are idle it might be better anyway as the overhead to scan all fd's might
become too large.
