I don't understand what all of the difficulty is.  Several UNIX 
and similar operating systems support both sync and async file I/O.
In fact, for those of you who are intersted, DG/UX does support
both synchronous and asynchronous I/O.  Furthermore, the semantics are
such that it is straightforward to use these features without many of
the shared sync/async gotchas.
