------------------------------------

I already signed your license and uploaded my patch.
If you look at the difference between a waitpid and wait4, you will understand my point.
It is not a question of stability and/or bug fixes. 
There is just no point in using a wait4 if you do not read the struct return (rusage).
Especially as wait4 is not present in all platform lib C.

best regards.
