One "hole" in each scan line to turn off blitter nasty?

Came across something today that I hadn't heard before.

Apparently there is one DMA slot per scan line that can't be used by the blitter under any circumstances. It was suggested that this was done to allow the CPU to turn off blitter-nasty if necessary.

Anyone know anything about this?
