mod_pagespeed causing high load on my server

[GoogleCodeExporter]

[entering this on behalf of the user who wishes to remain anonymous]

What steps will reproduce the problem?
1. Turning on mod_pagespeed and browsing the website
2. New site on dedicated server (there are no other visitors besides me), load 
average is usually 0.05 to 0.30. Turning on mod_pagespeed and browsing a few 
pages results in load average going up to 5.00 to 10. If I don't restart apache 
and continue browsing, this goes up to 30+ and crashes server.

What version of the product are you using (please check X-Mod-Pagespeed
header)?
1.2.24.1-2581
I have also tried the latest 1.4.X beta release with no improvements.

On what operating system?
Ubuntu 10.04.4

Which version of Apache?
2.2.14

Which MPM?
pre-fork

URL of broken page: REDACTED (see me)
