So the 'ring boundary' part still doesn't parse (neither grammatically nor logically) - please rephrase it because I have no idea what you want to say here.
Did you want to say:
> ... time sampling became jiffy based, even if it's still being context tracked, > so steal_account_process_tick() is reused to account how many 'ticks' are > stolen-time, after the last accumulation.
... which makes sense grammatically but does not make sense to me logically. :-/
Rik, Frederic, could you please help out?
Thanks,
