Have you tried installing a different httpd (such as lighttpd or nginx), 
to see if it's an Apache issue? If it runs fine on a different httpd, 
then you can "guarantee" that it's an Apache issue and not something 
else (PHP or otherwise). Another interesting thing you can try would be 
compiling Apache by yourself and testing with that, instead of the 
Ubuntu packages.
