Sorry, I misread your code - you can call isComplete() and then
submit. But, you have to check and act on the result of isComplete()
- the method does not _do_ anything, just tells you status. If it is
not complete you should not do anything with it, wait for it to
complete.
You also need to implement a pipe listener to get notification of all
these async-submitted irps coming back, or use a seperate thread.
