- `shell=True` implies `process_group=0` - make default `deliver_cancel` aware of process groups - backport `process_group` to Pythons prior to 3.11

Fixes #3237
If
shell=True, then it's possible that things we spawn will themselves spawn things. This is a problem because we only kill the parent process and those don't automatically propagate signals. We can solve this by default by making sure shell processes get their own process group which we subsequently kill.
