	OTOH, it should be possible to detect this relatively easily with a
simple test program; we can simply time a couple of lookups of your own
hostname, and throw up a warning at login time if it's a real problem.

	Having said that, I'm keen to know where we're doing that lookup, since
there should be no real need to do so; can you get an strace /
stack-trace of the offending lookup ?

	Thanks,
