Windows has the concept of "Overlapped I/O" which permits dispatch of an i/o
request that invokes a call back when done.
Posix has aio which functions (I believe) in a similar way.
So one has the concept of asyncronous i/o without any explicit reference to
threads at least at the application level.
In one I my projects I had occasion to use this. The windows API I found to
be (as usual) pretty unwieldy. I ended implementing a wrapper with the aio
So it does work and can be useful. On the otherhand, it does seem to me
functionally equivalent to multi-threading which is a more general and
perhaps simpler concept. So it may or may not be a good idea to encourage
its usage as opposed to threads
