--- Comment #4 from Andriy Gapon <avg at FreeBSD.org> ---
I've seen an issue like this in the past.  It was on a physical machine where
TSC locks were noticeably different between processors.  Unfortunately, right
now FreeBSD measures TSC differences only once and doesn't recalibrate deltas
periodically like illumos does.
