If you see multiple htcacheclean instances running at the same time then 
you know it's in trouble - they'll probably be saturating the IO 
capacity for your filesystem.

A load of 2! I dream of the days when my server had a load average of 2! 
I'm making do with a slow single-core machine at the moment, with a lot 
of very persistent site visitors, and our load average rarely drops 
below 50.. :).
