I don't know when you started, but when I started, on sys-III and
v7 in the mid 1980ies, that was exactly what people told you:
"Do disk-I/O in BUFSIZ units".

I did a quick sampling of src and that seems to be exactly how it is
being used in most of the cases I looked at, including libmd where
I put it there on exactly that reason back in 1994 (5?)
