Over time, Apache+mod_pagespeed memory grows to 8-10GB when using the graceful 
reload option.
The 'restart' resets memory usage but graceful is nice for production config 
reloads.

This is pretty easily reproducible, if you have vhosts and reload the instance, 
you should see memory grow.

------------------
I spent more time on this issue...and observed that the more vhosts are defined 
in httpd-vosts.conf the greater the memory leaks become with each apache config 
reload (i.e., -k graceful)

I tried turning off various pagespeed caching options but nothing really seemed 
to help.

This is not reproducable in older versions of mod_pagespeed (i.e., 1.3.25.4)

Fixed in https://code.google.com/p/modpagespeed/source/detail?r=3341

Note that this is still a problem in all binary releases between 1.4 and 1.6.
