Read up on fork-join, fork-join_any, and fork-join_none. You can disable any labeled block or task. You can also kill processes if you know the process id.

Your "After fork" won't execute until ALL three processes within the join complete. You likely want fork-join_any or fork-join_none.

Also, you only have three threads/processes (the three labeled blocks). Your $displays inside those threads will execute sequentially.
