(The bug report or code review for illumos 4518 talks about this.) I hope to have the next OmniOS bloody spun out soon, and then people can start keeping up with upstream again.

It is my understanding that ESX doesn't use NFS locking, they implement their own.
This makes sense, because NFSv2/3 locking has been problematic since the beginning,
from all vendors. Again, this is easy to measure.
