restarting the blitter in non hog mode this way is perfectly valid ; in asm, most routine will use the "TAS" instruction to do this and the atari doc does the same in their blitter examples.
The Atari sample code either uses TAS (in the newer docs) or BSET (the older example). Both _write_ to the LINE_NUM[BUSY] bit while Christian's code only reads it.
Not sure if that really makes a huge difference, though.
