If the only goal is to allow preemption, and if long grace periods are
not a concern, then this alternate approach would work fine as well.

Hmm.. if that were the goal I'd like it to have a different name;
cond_resched*() has always been about preemption.

BTW, I do not remember why cond_resched() is not an empty macro
when CONFIG_PREEMPT=y ?
