Can xenomai preempt its own system calls? We ran latency with our
app. We had a thread waiting on a cond, and when we signaled that
cond, the latency jumped from ~70us to almost 400us even though
latency runs a higher priority thread than the thread that we wake up.

Gilles and list,
I have tested out your latest patch with 2.4maint, 2.627.19. It
appears to work fine, no crashes related to 3dnow and no floating
point issues. However, we are observing rather high latencies. This
is without the hack described in the above thread.
