Whether it was the kill -9 that led to the corruption or whether the database was already corrupted and did therefore not respond we do not know; in any case, there seem to have been no alternatives to killing it (people on #mysql knew nothing either).

Looking at my irc log (which contains 4000 lines from 6/6 alone), it appears Tim started a second mysqld on the running database machine. In the future, do not attempt this. It takes a lot of setup to prevent them from stepping on each other. I don't know how much isolation there was in this case. (I know, because I've ran v3, v4.0, and v4.1 mysql's on the same machine. Along with half a dozen other databases :-) It's easier if you've compiled everything yourself.)
