45 The requirement is that the Notification from RT thread can be delivered... not sure using a pipe is adequate here...
46 Can the write operation block?
47 A non blocking write operation shoud be used : check if write can succeed, and ignore the notification otherwise
48 (since its mainly used for XRun, ignoring a notification is OK, successive XRun will come...)
