btw, what determines if a driver can allow mapped buffers during
execution?  Presumably it can't be cases where unmapping does some
sort of copy of the data?  What about cache coherency?  And also,
*which* buffers does this apply to?

(This would be, I guess, sort of more useful info to put in screen.rst ;-))
