While looking at Is it a good style to run external commands in Python?, I was surprised to find that there is currently no tag for [subprocess-management]. I also checked for likely synonyms such as [process], [fork], [exec], [spawn], [pipe], all with no luck. There are plenty of other questions that could use a tag of that nature.

I think that [subprocess-management] would be the best term to encompass all of the above, but am open to other suggestions.

There is also no [ipc] or [inter-process-communication] tag. Perhaps [ipc] deserves to have a tag separate from [subprocess-management].

To get this conversation started, I'm posting my proposals as answers below. Either vote on them if you concur, or post your own answers as counterproposals.
