I think that's a very good question.  It's analogous to
record-oriented I/O vs. byte stream I/O.  It's easy to build
record-oriented I/O on top of a byte stream, but it's a real bear to
do it the other way around.  Similarly, it's easy to build synchronous
I/O on top of asynchronous I/O but the reverse ends up looking
contrived.
