On machines where I don't have the stylesheets installed, it always
takes several seconds (2 or 3, I think, though I've not put a stopwatch
on it).  15 to 20 sec does seem like a lot, so it makes me wonder if
Paul's network environment is well-configured.

There's a nearby thread in which I was suggesting that we should just
not bother with this configure test [1].
