It is not surprising that that may work some of the time, or even most
of the time.  But occasionally it won't.

Twm is anything but "really complicated."

Any method which depends on other processes performing tasks quickly
is by definition a race condition and therefore not a correct answer.

In any case, I think I've come up with something that works reliably,
although I won't know for certain until the first time I see it fail
:-).

I'm hiding the window before realizing it, then repositioning it, then
showing it.  That is....

$window->set_usize($width, $height);
$window->hide;
$window->realize;
$window->set_uposition($x, $y);
$window->show_all;

This appears to work, at least so far.
