interesting to read - to me, if I'm allowed to bring up feature requests at 
this point, it would already be helpful to see at the end of all make 
outputs that at least one sub-make has failed - even if all other sub-makes 
ran successfully. Sometimes the error is hidden some 1000 lines of terminal 
output above... Maybe this output might be added with something like "-kv" 
(Keep going verbose)...

In addition the "token" feature that new jobs are allowed to be 
created/started sounds not bad. This would allow in case of an error in a 
sub-make to let all other running jobs finish, then safety "close" all 
pending sub-makes recursively (new return code) and finally print out an 
error message which sub-make has aborted (the one that killed the token), 
etc...
This should prevent "hard aborts" of running make rules and shut down the 
make process safely.

Best regards,

Erik
