It occured to me yesterday that a relitivly elegant way to accomplish this
might be to change the buffer cache so that blocks which hold data from
slow devices could be made swappable. Since the buffer cache and the swap
code seem to be fairly integrated at the moment, it does not seem like this
would be a huge change, and it is certainly prettier than having each slow
device have it own cache file, and it own cache manager (and its own cache
manager bugs). Have I overlooked anything important?
