Oil has an alternative way for managing processes.

The biggest difference is the =fork= and =forkwait= keyword which are blocks.

#+begin_src oil
fork {
  sleep 4
  write -- "Hello world"
}

forkwait {
  sleep 4
  write -- "Hello world 2"
}
#+end_src

- =fork= is the alternative to the =&= operator (e.g., ~sleep 6 &~) which can be blocked with the =wait= keyword.
- =forkwait= is the proposed alternative for subshells.
- =jobs= views the jobs and processes of the shell.
- =fg= brings a job into the foreground.
