Does this work with ExternalProject sub-builds? If not, I would suggest a big warning sign on the flag will save some headache... (my limited understanding of ninja's job pool implementation leads me to think not -- that would need jobserver support, the PR for which has languished. Would be very happy to learn otherwise!)
