The URL's at that site come back in well under a fraction of a second (there
is a typical one below). Are you saying that not only does the http server
send you a document, in then, after the document is sent, launches some
kind of job that then sits spinning in the background for two minutes?

Here is one of their URL's... http://xxx.lanl.gov/abs/hep-ph/9606274

Oh, and here's one for your homepage, it's certainly going on mine!

http://xxx.lanl.gov/seek-and-destroy
