* revert some of the overly zealous peer distribution code - select randomly from the fast peers, not according to a strict LRU
(which was causing lots of queued up tunnel requests, as well as tunnel failures when they all failed)
need to think some more thunks about how to address this right now. a few different algorithms available
to deal with different scenarios and #s of users, but nothing that by itself strikes me as 'ideal', yet. perhaps its
time for another trip to the pub to see what inspiration can be found there ;)
