I think doing the CLOBBER_CACHE_ALWAYS + CLOBBER_FREED_MEMORY runs in a
separate set of animals that does a single locale is enough.  It's
pretty dubious that there is any point in doing the CLOBBER stuff in
multiple locales.

Perhaps run these in HEAD only once a day, and do the other branches
once a week, or something like that.

If you add a seventh animal that does the recursive clobber thingy,
running say once a month, that could be useful too.  Since you have
spare CPUs, it shouldn't matter if it takes a whole week to run.

The advantage of doing this in separate animals is that you can run them
in parallel with your regular non-CLOBBER animals (which would run more
frequently.)
