I didn't write it but I did look at the code.  It doesn't check for retrace!
It works fine on my systems (PCAT with EGA and a Tandy 1000) which have a
properly designed display controller, but it will be bad news with real
IBM CGAs.

On the other hand, I get irritated by software which flashes the display
(and runs slower) to behave on the CGA!
