I get what you're saying but not seeing how to do that in make syntax. Mind giving an example?

  $ cat Makefile test: +env | grep MAKEFLAGS $ make -j4 test env | grep MAKEFLAGS MAKEFLAGS= -j --jobserver-fds=3,4 If you want to act like a sub-make, then parse MAKEFLAGS from your environment, and if you see -j and --jobserver-fds=R,W , then parse R and W as file descriptor numbers, block waiting for a byte from R before starting an additional parallel job, and write a byte to W when done with a parallel job.
