OK, sadly enough I always (have to?) work this way, and yes, it is
horrible. So I am looking for better tools.

Now it seemes that "small" extension of parallel cluster make would be
enough:

 ************ 
 Make should discover that some targets are already being built (by
 previou invocations) and can be obtained by just waiting for them.
 ************ 

(Of course, there still should be some acceptable load balancing.)

- Would anybody else be happy to have make with this feature?

- Anybody is working on it?

- Anybody HAS it ???

Thanks for your comments and ideas
