Note that some web servers and other networking programs that you
might want to use depend on setup_rt_frame.

It is used by code which uses queued SIGIO signals for event queuing
(it's the old "scalable I/O" method before epoll replaced it), and
it's also used by code that uses dnotify to check for file changes.  I
think Samba may also use it in conjunction with F_SETLEASE.

Since you seem to be aiming at networking support, I thought to
mention this...

Enjoy,
