Returns a pair of fds (status_r, data_w). The calling process can read
the child process's pid and (eventually) its returncode from status_r.
The calling process should write to data_w the pickled preparation and
process data.

This can be called from any process. Note that usually a child
process will just reuse the forkserver started by its parent, so
ensure_running() will do nothing.
