MEDIUM: queue: unlock as soon as possible

There's no point keeping the server's queue lock after seeing that the
server's queue is empty, just like there's no need to keep the proxy's
lock when its queue is empty. This patch checks for emptiness and
releases these locks as soon as possible.

With this the performance increased from 524k to 530k on 16 threads
with round-robin.
