This is a context manager intended to let you imitate the as-CLI
behavior documented in the module docblock. See that docblock to
understand the process-spawning chain.
- `cmd` is the post-sudo command, to which you want to pass the FDs.
This may invoke `systemd-nspawn`, in which case you will want to set
`set_listen_fds` to `True` if you need the FDs to be delivered
inside the container.
- `fds` are arbitrary FDs that you must not close before this context
manager produces a context variable.
- `popen` is a callback returning a context manager that works just
like `subprocess.Popen`. The only difference is that normally this
callback will prepend its arguments with a `['sudo', '--some',
'--args', '--']` invocation.
