It's possible that the "master thread" died and left some worker threads
hanging around that still have the port open.  Use ps to determine if
there are still mysqld's running, and kill them if so.

Of course, MySQL should never end up in this state, so if you see this,
report it as a bug.  It probably wouldn't hurt to upgrade to the latest
version first.
