Avoiding <exiting> processes on Ultrix

[Jamie Watson]

I know this sounds trivial, but I have searched the Ultrix (and 4.3)
manuals everywhere I can think of, and I can't find the answer.

Is there any way under Ultrix (2.0 or later) to write a C program
such that any child processes created by that program will exit,
without hanging in an <exiting> status until the parent does a wait()
for the child?  Under SysV this is done with signal(SIGCLD, SIG_IGN);
I have tried that under Ultrix, to no avail.
