go using them all over the place if you don't have to. They're also usually
written more to be compact in terms of code than for raw speed, so you actually
can out speed them in some cases. Between the increased overhead and not being
as speed optimized, you can sometimes do a faster job without calling the BIOS
at all. (TODO: investigate more about what parts of the BIOS we could
potentially offer faster alternatives for.)
