Be able to group/tag processes

[marianopeck]

From Max Leske

The use case I have in mind is again ImageMagick. Imagine I want to kill all processes that invoked ImageMagick, and those invocations are strewn across the code base. Also assume that I invoke another command often, say curl. I want to be able to kill all ImageMagick commands or all curl commands at once. That means I would have to track child processes separately for both (or in some kind of centralised object). If OSSubprocess had a facility for grouping the only thing I’d have to do would be to add something like #groupAs: #imageMagick when creating the process. I do see that this may take some work. I also concede that it’s not something terribly necessary. I just though it could be nice (think of CGroups for instance: https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt).

Max, would you agree that instead of groupAs: a tag: could do the trick and since it's quite general it might have other use cases besides grouping?

Yes, definitely.
