High number of git cat-file processes in CI
From https://gitlab.com/gitlab-org/gitlab-ce/issues/58882#note_177948373, we observed 42 git cat-file
processes running in a CI environment. This takes an estimated 28 MB * 42 = 1.2 GB of virtual memory and may be contributing to the random resource errors we've been experiencing this past week.
@johncai Is the git cat-file caching misbehaving?
