You should add a function in tick-sched.c to get the next tick. This
is supposed to be a private field.

Just to make it clear. Neither the above nor a similar check in
tick-sched.c is going to happen.

This busy waiting is just horrible. Get your act together and solve
the problems at the root and do not inflict your quick and dirty
'solutions' on us.

Thanks,
