Note: fix uint locker

[yunginnanet]

Probably should make a net.Conn implementation that stores the unlock pointer upon conn.Close or something, it appears I'm unlocking these things after we grab them and determine them suitable for use. With the new refactor they should be popped from the list and not available for use anyway? needs more investigation. leaving this issue here so I don't forget, but as always with open source; pull requests welcome.
