The v2 removes a couple of redundant checks from the first patch (and add
comments to explain why the checks are not needed) and fixes up the
"no constraint" value collision with a valid constraint multiplied by
NSEC_PER_USEC in the second patch.

Please test if possible and let me know about any issues.

Thanks,
