A small (but probably non-useful) comment:
I originally envisaged buffering as being a strictly file-based thing - a
layer on top of file i/o, rather like dircache.
You'd "bufopen" a list of files you were planning to read and it would
attempt to pre-read them into memory. You'd then "bufread" the data which
could come either from the buffer (good!) or from the disk (bad, but
inevitible sometimes). Then, when you're pretty sure you no longer need a
file, you'd "bufclose" the buffer handle. Internally, the allocation would
of course have to make judgements about discarding buffered data as and when
new space was needed, using the hints given via the file type.
However, it seems to have become malloc-by-proxy. :)
