[pLog-svn] Process size

[Oscar Renalias]

I guess it's the same issue we had in devel.lifetype.net.

One thing you should check is whether you've got any user who has  
configured his/her blog to display something like 80 or 100 posts in  
the front page, as that can cause performance problems. There's  
already a fix for that in LT 1.2, but in the meantime you will have  
to keep an eye on it on your own. Otherwise a crawler performs the  
exact same operations as a user via a browser would do.
