Some clients (Debian-x86 unstable tla-1.2-4) use the cacherevs as

(Debian-amd64 unstable 1.2-4 and 1.3-1) ignore cacherevs and build
everything from "base-0" upwards. This takes a few hours and 10GB, so
I'd rather avoid it.

The library-add algorithm prefers to use library revisions, and will only use cacherevs when
- there's no ancestor revision in the library or
- building from the ancestor would invove crossing an archive boundary

The devel baz 1.3 uses the backbuilder algorithm for all revision building, so it will use cacherevs, if they're 50 revisions closer than the nearest library revision.
