While I do not think this is wrong per-se (i.e. it is clear that we
no longer need revs.commits), after this the function will return to
the top-level caller and exit immediately, and I do not see anything
that desperately wants to use as much memory as available (i.e. would
be helped by this piece of memory released early).  "the biggest"
may be an overstatement ;-)
