Deleting a MultiInstanceLoop sub process

HiI have a use case wherein I need to be able to 'delete' or immediately end a subprocess created from a multiinstance loop. I tries using the deleteProcessInstance API in the RuntimeService. This works fine but because the multiInstance loop run sequenctially it doesnt create the remaining subproce

Please disregard the above issue. There was a error in my tests. The sub processes do get created in parallel. But I have found another issue which on the surface looks like a bug. If I delete a sub process created by a multiInstance loop the parent process waits indefinitely for the killed sub process.
I think when deleting a process, activiti should check if the process being deleted has a parent execution and if so update its loop variables (nrOfActiveInstances, nrOfCompletedInstances), so the parent doesnt end up waiting for a process that has been deleted. Does this sound right? Please confirm if I should open a bug for this.

Please let me know if I can provide more information or if I am unclear about the issue. If someone from the activiti team can just confirm whether this is a bug or not I can go ahead and create a jira issue for this.

Im not sure if it's a bug or 'by design'.
Immediately deleting the process manually sounds like an edge case. Or do you mean that the called process goes into an end state?

Could you provide a unit test with a simple process that demonstrates your use case, that would clarify a lot.
