I was talking design. Anything that requires user interaction is by
definition non-realtime, so, if you have the choice to leave it out of
the RT domain, do it. You'll save a lot of headaches.
Of course, if your GUI is so tightly coupled to your RT processing that
you cannot do without rt_mutexes and/or other sync primitives, then you
must map it to Xenomai.
