The problem was that the handle was opened with the
FILE_SYNCHRONOUS_IO_NONALERT option. This caused NtDeviceIoControlFile to do
an internal wait if the driver returned STATUS_PENDING. As a result,
STATUS_PENDING was no longer returned as the status by NtDeviceIoControlFile
to msafd, so the waits in msafd were bypassed.
I've attached the proposed patch to bug 713. No comments so far.
