Bug fixes and recoding of mon-paging.c. Some of the comments
for the mods need to be changed. I'll do that next.
Added an acceleration for INSW, transfer is done in user space
potentially in blocks of words direct to guest memory. I notice
FreeDOS boots from the disk image file in only a few seconds
after this mod. :^) This only helps if you do a REP INSW, which
the BIOS does. Could extend this method to other instructions.
Gives us an idea what special data transfer can do for performance.
This should model the kinds of gains we can get with special
guest OS device drivers.
VCode cache entries are invalidated individually. Before I was
dumping the whole set when one got stepped on.
