good point.  can we just make i/o unit anything we wish?
maybe it's old 9p hangover, but i have this nagging feeling
about network-dependant limits.

in looking at the code, it might be a lot more efficent
for loadimage to count pixels rather than lines (being
careful with the slop at the end, of course).  the
slop is Dy(r)-1 pixels, which is considerable for a
camera shot.

maybe it's not worth the pain?
