Just me being
a) brain dead
b) too brief.

Henrik's later email aligns neatly with my proposal.

The basic thing is, the null cache dir is a workaround for two
behaviours of squid. Namely squid requires a cache_dir to operate (a),
and defaults to a ufs cachedir of 100 Mb if none is specified (b).

Addressing (b) is easy, we change the default to be no cache dir.
(a) will take a careful code review, and thats about all.

Having no null cache dir will allow a somewhat stricter SwapDir class
definition, and will reduce the number of cache dir code paths to
maintain to 2 - coss and ufs.
