detaching jobs via rsh

[Per Foreby]

I'm trying to start a xterm on a MacII via rsh from a sun. I do it via
a small program which forks a child and then does the following:
	set42sig();
	setpgrp(0, getpid());
	ioctl(...,TIOCNOTTY,...);
	execvp(....);
On any other *ix where I have tried this, it works just fine. But on
AUX I get the following result: 

    root  6766    70  0 14:14:42 ?        0:00 in.remshd c0247b0b.1022
    perf  6767  6766  0                   0:00 <defunct>
    perf  6768     1 11 14:14:47 ?        0:02 /usr/new/X11/xterm -display ...
    perf  6769  6768  2 14:14:57 p0       0:01 -ksh

The remshd does not wait for my program, so even though it looks like
the xterm is "on its own", the rsh hangs. On the other *ix i get a
<defunct> process for a while (until the xterm has freed itself).
Obviously there is still some connection between father and son, but
what?
