pre-2015 can be clarified a bit:  r151014 and later has the modern ZFS write throttle.  Now I know that Stephen is running later versions of OmniOS, so you can be guaranteed it's the modern write-throttle.

Furthermore, anyone running any OmniOS EARLIER than r151014 is not supportable, and any pre-014 release is not supported.
