Supporting Asynchronous FileStream Class

Well dang, the current constructor NewFileStream() doesn't include the useAsync optional argument with the intent to implement it later. So now I have a dilema. I have 3 options:

1. Break Binary Compatibility to include the new argument.
2. Add a second constructor NewFileStreamAsync(), keeping Binary Compatibility.
3. Don't add asynchronous I/O capabilities to the FileStream class.

So now I'll be thinking about it....
