sched_clock() probably isn't suitable for this application. It's a
scheduler thing and has a number of accuracy problems.

But I thought we discussed this last time around? Maybe not.

Maybe you've considered sched_clock()'s drawbacks and you've decided
they're all acceptable. If so, the changelog should have described the
reasoning.

But even if so, sched_clock() isn't something we want to be exporting to
modules.
