https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      aiomultiprocess presents a simple interface, while running a full

+      concurrency never before seen in a Python application. Each child
+      process can execute multiple coroutines at once, limited only by
+      the workload and number of cores available.
