AbortIO NEVER removes the request from the reply port.  All it does
is try and get the device to stop processing the request.  If the
request was actually aborted then the io_Error field will be set
to a characteristic value.

Also note that AbortIO() is not guaranteed to abort the IO immediately.
The device may be committed to completing that operation, and be too
involved to back out of the transaction.

Yes.
