Ugh, first I've heard of this bug. So, in an httpd-"accel" setup,
we're wasting more bandwidth than if we didn't use squid at all!?
Can anything be done in the config to mitigate?
Is the STALE state always refreshed by a IMS request?
Is there a way to force a purge/re-get instead of an IMS?
i.e. It'd be nice if lm-factor > percent generated an IMS,

If not, perhaps I'll write a tool to tail the log for the hottest objects,
look at the headers on disk, and issue PURGE requests. Yuck.
