This stackoverflow answer[0] shows how you can queue jobs even after you start running other processes in your queue. Essentially, you can do:

  sleep 2; echo "A" && sleep 2 ; echo "B" && sleep 2 ; echo "C" 
  # Quickly Ctrl-Z
  fg && sleep 2 ; echo "D"

and you will see A\nB\nC\nD\n slowly printed out in your terminal.
