Decrease MCLBYTES from 4k back to 2k. It isn't likely that we'll be doing
page flipping anytime soon and 4k just wastes memory. Performance via the
looback interface will decrease slightly by this change. Idealy, we need
buffers that can have variable sizes, but this requires a rewrite of far
too much code at the moment.
