PS: if you go for user-space support, take an extreme care to properly
propagate the -EINTR return code to the user-space caller (see XNBREAK
condition upon return from xnsynch_sleep_on()), signaling that a Linux
signal has hit a blocked real-time thread. Doing this properly
guarantees you a working GDB support for debugging the apps using your
interface, and above all, participates to the overall stability of the
system upon signal receipt. Keeping this in mind will spare you a fair
number of head banging sessions.
Thanks for the hints; let me try my hand at it once again.

Pramode
