	I am writing a motif application which manages a unix software package.
Among other things my motif application spawns off other unix processes 
(daemons) which will continue to run after the motif program is terminated.
I am using system(2) to spawn of the child processes.
The problem I am having is that after I start one of these daemons my motif
window does not go away unless all children are terminated.  In other words, 
the unix process terminates but the window hangs arround.  When I do a `ps -ef`
I see the child processes all with parent process ID of 1 and no shell or any-
thing to be keeping the window up.  
	Is this a bug in motif, X, or mwm?  If not, what do I need to do to 
make the window dissapear?  I have tried ignoring and releasing the SIGCLD 
signal, but, there was no difference.  I have also tried using fork(2) and 
exec(2) but that made no difference either.
