It has to be something with the 1.4 JVM on my XP box, since from the docs
it's using j.n.URLConnection.  What I see is a low thread-count on the Java
Connector, which means that there aren't very many connections active.  With
the HTTPClient, the thread count happily goes up to the number of threads on
the test.

My test box is Solaris7 (the shiny new ones are in production, so I can't
use them for testing :).  It would be interesting if somebody could try it
out on a version that isn't a museum piece ;-).
