No, it isn't working.  We had an outstanding bug report in VM and Tim 
has finally tracked it down to this problem.

VM is calling force-mode-line-update in a Folder buffer, which is 
generally invisible.  The function is updating its menubar, but not that 
of the currently visible buffer.  Even after I change it the way I 
mentioned in my previous post, it still doesn't work because the 
"other-buffer" also turns out to be the Folder buffer for some reason or 
the other.

That would be logical, but I am guessing from force-mode-line-update's 
doc string that this has the effect of updating the mode line, menu bar 
and the rest.

It is a pity that set-buffer-modified-p's doc string doesn't do justice 
to all that it does!
