The trackdisk driver as originally written did have more than 1 track
buffer. We had to limit it to 1 though to keep all those 265k
systems working.  Maybe it is time to rethink this strategy and let it
loose again. It should probably check the available memory at power on
and automatically grow it trackdisk cache. Adding a new command like
addbuffers for us programmers would be good as well.
