On ST and Falcon it should be valid to start the blitter in non-hog mode and leave it running, without restart. It will restart itself every alternate block of 64 bus cycles until complete.

I wouldn't not steal the thread but using Non HOG mode without restarting has a side effects on blitting performance.
This is because of BLiTTER's specific behaviour in NonHOG mode. More details there

Below my figures for blitting on real hardware - Falcon and STE, both in "ST High" mode:

Hog Mode:
F030: 2,93 MB/s
STE: 1,98 MB/s

Non Hog mode _without restarting_:
F030: 0,75 MB/s
STE: 0,90 MB/s
