Argh.  I seem to have mis-communicated myself horrendously.

Urxvt *is* obeying the size xmonad gives it, because I'm using

(old) Tabbed is displaying all windows, but relying on the focused
window's position in the Z-order to prevent others from being visible.

This is very fragile, and with LayoutHints it is possible to see other
windows; this is a major annoyance because of the interaction with mouse
focus.  (moving to lower right makes firefox pop to the top and I have
to mod-j)

The behavior I would like to see does not involve any explicit
unmapping, but rather simply omitting them from the list of windows that
should be visible.  (Don't you just love functional style? :) )

'full' already exhibits the behavior I want.

David Roundy did not want the behavior in (old) Tabbed, for reasons I
did not understand and did not like.

My question was whether New Tabbed did what I wanted.

Yesterday on IRC I threatened a fork.

With the benefit of sleep I have a *much* better idea.

If New Tabbed doesn't do what I want after my next upgrade cycle, I'll
add a boolean configuration option.

No big deal.
