runtime: yield instead of sleeping in runqgrab on OpenBSD OpenBSD has a coarse sleep granularity that rounds up to 10 ms increments. This can cause significant STW delays, among other issues. As far as I can tell, there's only 1 tightly timed sleep without an explicit wakeup for which this actually matters. Fixes #52475.
