The win32 API has ReadFileScatter/WriteFileScatter, which was developed
to handle these types of problems. These two functions were added for
the sole purpose of making SQL server run faster. They are always
asynchronous and are very efficient. Perhaps the win32 port could just
deal with the synchronization with an eye for future optimizations down
the line?
