Sounds good - but I doubt the complexity it adds would really be worth
it.
If the real problem is the C++ compiler or other large tool needing
sufficient resources that you have to ensure invocations are
sequenced/throttled, then the obvious solution would seem to be to
invoke it via a proxy that can do the the needed throttling on a global
(system, user, or whatever basis seems to make sense).
Think of make's invocation of ${CXX} as actually just submitting a job
to the CXX service, which might only be allowing one instance of C++ to
run at a time.
