I have an application that is reparenting Epoch screens, and I'm
having some problems with it.

I'm running mwm, Motif 1.1, X11R4, on a Sparc IPC with SunOS 4.1.1.

The first problem is that if the target window is mapped, I can't
reparent it. If I make sure that it is unmapped before my application
tries to reparent it, it works. The target window is a toplevel window
before the reparenting. Also, if it's mapped and I try to reparent it,
it gets unmapped, but not reparented. Doing an unmap right before the
reparent doesn't work either, although it also unmaps the target
window.

Second, when my application exits, the target window is destroyed.
I've tried using XAddToSaveSet() and XChangeSaveSet(), but they don't
seem to have any effect. Do save sets actually work? This happens with
both XCloseDisplay() and XtCloseDisplay().
