Ah, I missed that bit because the original message was all on one line and
ran off the end of the screen.
Put something like this in the parent program (cut & pasted from npanel):
#include <signal.h>
#include <sys/wait.h>
void reaper(int signum) { while(waitpid(WAIT_ANY, NULL, WNOHANG) > 0); }
Somewhere in your initialisation routine:
signal(SIGCHLD, &reaper);
What this does is calls waitpid() to reap the dead children when it gets a
SIGCHLD signal (triggered whenever a child exits).
