Details
We currently have MOZ_DEBUG_CHILD_PROCESS which pauses all children and waits for you to attach a debugger.
On OSX at least, that's getting pretty painful as a reftest run usually launches 6+ processes, and you need to attach to each of them manually (using lots of terminal tabs).
Fission is going to make this even worse.
I think that we could add an env var that specifies which process types (rdd, gpu, tab etc) you want to be paused for debugging, as a comma separated list of strings, compared against the list in GeckoProcessTypes.h.
We could also add something similar, but with a list of origins (partial matching?) so that you can debug specific processes when fission is enabled.
