Hello @gimler, thanks for your work. Your goal here is to "modify the command based on the previous finished". It looks like you are trying to accomplish a sequential process execution. This simple wrapper was meant for parallel processing. Let me know if there is something that I am missing from my understanding.

Actually i have 4 phantomjs instances and n testcases. Each phantom has his own port and should only execute one test a time.
So i must manipulate the command before when i know which phantom instance is free.

Actually i have three events before after and processing.
