Seems we're still running into this on the CLOBBER_CACHE_ALWAYS animals.
The problem is that the git mirror is refreshed only at the very
beginning, and while a single branch does not exceed the limit, all the
branches do.

Could this be solved by keeping a local mirror, without a mirror in the
build root? I mean, something like this:
   git_keep_mirror => 0,   scmrepo => '/path/to/local/mirror'

And of course a cron script updating the mirror every hour or so.
