timestamp set when it's opened. Older copies with the same socket can be tested against the cannonical copy maintained by tpool and sending avoided when the timestamp shows the endpoint has likely changed. Change tpool's list of sockets to a map for faster lookup, and get rid of similar structure in udpqueue.
