The primitive I/O layer, besides offering more control over
performance, also allows you to create access to arbitrary data
sources easily.  Scheme systems have traditionally done this at the
ports level, but it is difficult to get right there.  (For
entertainment value, look at the interface in the PLT v3xx series.)
