DISPATCH-577: Fix latency regression introduced by commit 6e6929c
That commit introduced sporadic high latency messages, caused by insufficient
polling. This fixes the problem and is still fairly conservative: it checks the
need to re-poll before read/write processing rather than after, which could
result in at most one extra poll when the transport becomes
un-readable/un-writable.
> Server logs show unexpected POLLNVAL errors.
