vmaffione 374d058de7 ThreadPool: optional limit for jobs queue (#1741) ...

For very busy servers, the internal jobs queue where accepted
sockets are enqueued can grow without limit.
This is a problem for two reasons:
 - queueing too much work causes the server to respond with huge latency,
   resulting in repetead timeouts on the clients; it is definitely
   better to reject the connection early, so that the client
   receives the backpressure signal as soon as the queue is
   becoming too large
 - the jobs list can eventually cause an out of memory condition
