Interesting! I didn't know that -

Yup. And also very clear that we believe that filters are quite leaky
-- meaning that they will have problems with it, and a plan / process
to deal with it. Some local teams may find planning for such
situations hard.

Yep - TURN_SQUID_ON works well on the current xs-0.5 dev version.
However, I'm not very happy with it due to memory footprint, and
considering replacing it with a apache + mod_cache_disk which - from
what I've seen - plays to the strengths of linux's disk i/o handling.
