  --- BEGIN ISSUE ---
  importing distributed runs 4 `git` subprocesses in CI (when installed with -e)
  I noticed that tests that run a dask subprocess are often flakey on CI (especially so on low performance macos runners)
  
  https://github.com/dask/distributed/runs/4922796526?check_suite_focus=true#step:12:1849
  This is an example of a process taking more than 5 seconds to boot on a mac in `test_dask_worker::test_memory_limit`:
