Consider the following simple program:

#include <signal.h>

handler()
   {
   signal(SIGCLD, handler);
   }

main()
   {
   signal(SIGCLD, handler);
   if (fork() == 0) exit(0);
   }

When I run this on my Sys Vr3.0 system, it goes into recursive
death.  As soon as the handler calls signal to reestablish
itself, it is immediately reinvoked.  Am I doing something wrong,
is my Sys V broken, or is Sys V just generally broken?
