One remark I forget to mention. If no WM runs, XWM don't tries
to getInsets, because that won't make any sense obviously...

So also the question is clear now, why don't manage() windows
(only mapping them) doesn't works, because of such insets. It's
also clear why wmii, evilwm and larswm work fine: because those
do reparenting...

It is up to the dwm userbase now, to make pressure to Sun to fix
this bug (it might also be related to compiz, because that also
don't reparents anything, it composes only afaik). For me, I
don't care, because I have given up using Java after all.
