Dave and I talked about the changes needed to allow uncaching when a file is
truncated. It's only tedious, not hard. See the treatment for removal if
you want to see what's involved.

We could leave the default the conservative one, and allow switches to be
passed to specify the other.

This requires boot.exe hackery, but since we want to increase the buffer
size I have to break out Borland C again anyway, so I may as well enhance it
to allow some flags to be passed. I think we also want a flag to indicate
MGA text for the on-screen kernel debugger.
