Thanks to valgrind and his --track-origins=yes option,
the problem and solution was suggested as shown below.
[ and it was created in that commit referenced below ]
But, after attacking this problem by adding a memset()
call in pids.c, a 2nd valgrind oops, also shown below,
was encountered. The dynamically acquired 'cmd' again!
[ might help to explain why changes appear excessive ]
