Say if I have 10 tasks I need to run, is there a way I can make sure tasks 1-9 are complete (in any order) before task 10 is launched?

Hi Paul,
It's possible to launch a task from another task. This means each task 1-9 can check if the work from the other tasks has completed, and then launch task #10 if it is. Task #10 should check to see if it's not already running (singleton). Be careful to avoid having a task launch itself as this will lead to a condition called a fork bomb.
Cheers,
Adam

How can you check for an existing running Task (in PHP)?
Is there a way to "label" a task or do you have to check for its ID?
