clock are supported. I have plan to merge XSI timer ITIMER_REAL and other two CPU timers into the new code, current three slots are available for the XSI timers. The SIGEV_THREAD notification type is not supported yet because our sigevent struct lacks of two member fields: sigev_notify_function sigev_notify_attributes I have found the sigevent is used in AIO, so I won't add the two members unless the AIO code is adjusted.
