I have a vague recollection that early time sharing systems, in particular
UNIX, enforced I/O fairness by fragmenting files and thereby freeing the I/O
between fragments. However I don't recall much and this might be an
artifact of aging :-)
If so, I am curious as to how this was implemented - interleaving sectors or
some more complex physical fragmentation or ??
Anyone point me to any references?
