to work around earlier LIMITED design.
IFF 64K is reasonable for you, then x86 is excellent.
If you barely need a little more (a few 64K blocks), then it is OK.
(such as XenoCopy)
If you really need more, then it is a PITA.
Keep in mind, that it was coming into a 64K world, and wasn't intended to
last much past that.
If you are trying to use a 64K address processor in a multi-megabyte
world, it's going to be a miserable misfit.
(like trying to use an air-cooled VW bus for commercial hauling)
Yeah, we use what's handy, even if it's not really suitable.
