However much of a kludge HyperThreading is, and I don't doubt that it's
a horrible kludge, performance on my 2.4 GHz P4 has improved
dramatically since I enabled it.  When I'm running two CPU-intensive
programs at the same time--an extremely common situation--latency is
much less of an issue.  I'm really happy with the results, even if the
design is awful.  But when dual-core processors become affordable, I'd
love to get one.
