Seems like a much better way, yes. Especially if we in the future want
to do this for more than one platform (if it becomes necessary).

Yeah, I think core is better. It's not like it's enough code to cause
a huge maintenance problem, I think.
Do we need to make the value configurable? I'd certainly find it
interesting to set backends to say 5 or something like that, that
makes them less likely to be killed than any old "oops opened too big
file in an editor"-process, but still possible to kill if the system
is *really* running out of memory.
