While you can, you really, *really* shouldn't. pthread_kill was one
of those things that seemed like a really bad idea at the time but
went into the standard under pressure anyway. Killing threads is a
good way to leave the entire application in an unstable state and
have it die a horrible death.

If you want a DNS lookup with timeout, you may have to go roll your
own lookup library. (or find one that someone's already done--might
want to look around Freshmeat.net) While not trivial, it's not that
tough to do, as it's just a UDP client.
