This is true, but in this context, is it useful?  If one wants multiple
displays, one can easily double the height or width of the virtual
display and run nested servers inside of them.

I think, perhaps, the more useful thing is to allow multiple remote
clients to connect to individual displays... which this patchset has not
quite achieved, but proved at least plausible.
