net.server_epoll: Add support for opportunistic writes
This tries to flush data to the underlying sockets when receiving
writes. This should lead to fewer timer objects being around. On the
other hand, this leads to more and smaller writes which may translate to
more TCP/IP packets being sent, depending on how the kernel handles
this. This trades throughput for lower latency.
