my goodness! a felicitous discovery

Haven't had much time to do anything other than apply to Ph.D. programs, finish up my MS, and hack on libtorque, but OpenSSH connection multiplexing is just too awesome not to trumpet (nevermind that it was introduced in 2006, gah!):

Those are some pretty solid improvements, folks. I've got a minor writeup here, or just read ssh_config(5). Oh yes: I quit McAfee Research 2009-11 to pursue academics full-time. It was a great five years there, and I appreciate all the good times. Back to my HotPar 2010 submission!
