Actually, bitbucket should be doing this. Although I can't quite
rule out the possibility that we reenabled GC in this repo some
time ago.

Indeed. Unfortunately this isn't easily reproduced in the test instance,
so I will need to get a newer git under the production bitbucket.

There are quite some of

          \_ /usr/bin/git receive-pack /opt/apps/atlassian/bitbucket-data/shared/data/repositories/68
          |   \_ git gc --auto --quiet
          |       \_ git reflog expire --all

in the process tree, apparently a new one gets started even though previous
ones are still running. The number of running expires grew slowly, in the
order of many minutes.
