-; Clears prefetch queue by jumping to next instruction.
-; This delays much more than nop instruction of fast systems.

-; JMP_DELAY
-;   Parameters
-;       Nothing
-;   Returns:
-;       Nothing

-; Mimimun delays (without fetching) with some CPU architectures:
-;   8088/8086:  17 cycles for jump + 5 cycles for last comparison
-;   286:        10 cycles for jump + 4 cycles for last comparison
-;   386:        13 cycles for jump + ? cycles for last comparison
-;   486:         7 cycles for jump + 6 cycles for last comparison
-;
-; DELAY_WITH_LOOP_INSTRUCTION
-;   Parameters
-;       CX:     Loop iterations (0 is maximum delay with 65536 iterations)
-;   Returns:
-;       Nothing
-;   Corrupts registers:
