From: Greg Funni <gfunni234@gmail.com>

WAIT_FAILED is the only real possible error here.

WAIT_TIMEOUT would not be returned as the INFINITE is given to the call.

WAIT_ABANDONED would be returned if the handle pointed to a mutex object that was not released by the thread that owned the mutex object before the owning thread terminated.

WAIT_IO_COMPLETION would not be returned because we pass FALSE so the wait is not alertable.
