Thank you for the clarification. Modifying `runtime->delay` from the `pointer`
function looked wrong for me. Now I understand the motivation and the use-case.
I will be more careful when analyzing the code which doesn't fit my 
expectations.

@Mike

I was wrong. You can ignore my comments. Please don't take them personal: it's
all about having high-quality code in kernel.

Best Regards,
Kirill
