I need to schedule a script many times.  I assumed that if I scheduled it 10 times they would just stack up and be processed in the order they were scheduled.

It seems that if a deployment has a scheduled status of "IN PROGRESS" and you try to schedule that deployment again it will fail.

I really hope that I don't need to create a "pool of deployments"!

So to summarize: I schedule script 'abc' deployment '123'
I schedule it again while the first schedule is running and this seems to result in the second scheduled event being ignored.

What is the best practice in this scenario?  It's possible that with each user of my desktop application I could schedule up 20 deployments per user, per operation.  These are short running scripts so I'm not concerned about the volume.
