Well, in my case it's 50 messages pending action in my mailbox, but the
effect is much the same.

Sez who?  Not to sound argumentative or anything (:-), but I was
thinking about it the other day and I realized that my window manager
has no need to select for SubstructureRedirectMask.  Its policy is to
let windows do anything they want with respect to where and when they
appear, how they resize or restack themselves, etc, so what does it
need substructure redirection for?  Nothing.

I think its obviousness blinded you :-); I would have brought it up
myself except that I think it's not true.  (If there is some reason why
a window manager *must* select for SubstructureRedirectMask on the
root, I'd like to hear it.)
