make the problem more reproducible
Specifically, it hangs if ntoskrnl is able to signal that the IRP is pending
(by calling get_next_device_request) before the user space process calls
wait_async().
97afac469 intends for wait_async() to return STATUS_PENDING, because that is
the synchronous return of the ioctl. The problem is that we're trying to have
the select request *succeed immediately*, but STATUS_PENDING means that it
didn't succeed immediately and that the client needs to wait for a wakeup.
This can be triggered pretty reliably by running the relevant tests in a loop,
as in the attached patch.
I think
<https://testbot.winehq.org/JobDetails.pl?Key=92616&f401=win32.report#k401> is
an example of this happening on the testbot.
