Not my area of expertise, but I'd bet a few eurocents both of these
must be caused by a race condition of some kind, where Emacs idea of
the frame state and the window manager's idea are desynchronized.
Creating and modifying frames is relatively slow. Bug#16967 is such a
case, on Windows.

That's wonderful, because we have finally decoupled the bug from
framesets (which makes things easier to test).

So, at the end, the bug is that modifying the dimensions of an
existing frame with tool-bar-lines set to 0 fails. That's either a
window manager problem, or a problem in the Emacs code related to it.

Adding a workaround for frameset.el is possible, but I'd like to know
if it's possible to fix the bug for real, because any workaround is
going to be ugly; I can't just disable the current code because I'd be
trading one bug for another.

Martin, any suggestion? Anyone else who knows about this stuff?
