That is most likely a bad idea. I'm wagering MySQL's thread killing
is cooperative, that is, it probably checks during each phase of processing
whether or not it has been killed, and if it has, to safely clean up.
Forcibly terminating a thread where it has no choice will not
allow cleanup routines to run, which could cause undefined behavior
or at the very least resource leakage.
These are just guesses though.
