BTW: I should have mentioned that this test cannot be done with the original 
Bourne Shell, as there, the script would need to contain:

        trap 'c=`expr $c + 1`' CHLD

and this would cause a SIGCHLD storm as a result of the end of the "expr" 

Depsite that fact, the original Bourne Shell could also be seen as compliant.
