tests using multiple processes

[Peter Johansson]

Hi automakers.

I have a test-suite (with automake parallel) in which some of the test 
cases run multithreaded applications and therefore use eg four CPUs. In 
order to avoid total overload I currently reduce number of jobs e.g. 
'make -j2' rather than 'make -j8', which is sort of waste because it 
means that for part of test the load is only 25%. Is there a way/trick 
anyone has come up with to tell Make that "OK this test should allocate 
4 jobs, while these jobs only need one job each".

Cheers,
Peter
