I know that: rtl_fifo.o and rt_monotonic_sched.o, then my module on
top of these two. I did some debugging and based on that I concluded
that everything seemed fine until rt_task_make_periodic() was invoked
(with the correct argument). Maybe there is some incompatibility
between rtl_fifo and rt_monotonic_sched, because the latter replaces
all the functions of rtl_sched, but it might have different data
structures from those that rtl_fifo expects... although the
rate-monotonic example seems to work as it should.

I need to learn how to use Z. There are actually 16 fifos, maybe I
could permute them just to see what happens.
