Right, Patrick's series only makes the gc run less often. The lock
itself is the subject of

  [PATCH v3] rerere: keep a background gc from killing a rebase
  <pull.2214.v3.git.1788537081930.gitgitgadget@gmail.com>

where setup_rerere() waits rerere.lockTimeout for it and then goes on
without rerere, and a gc that finds it held gives up at once.
