I would suggest using this undocumented API call under an 'if' condition, which is controlled by a command line option for selecting based on unique ID. In that way setups which prefers stability can choose to not use this feature.

I tested it with 10.9.10 as there were (non-related) regressions in 10.10, and it worked fine there, so I figured it should be OK to require only 10.9. If you still think using a non-documented feature is shady, I can bump the requirement to 10.10.
Thanks for the clarification. In that case the current patch is fine, since you have testing it for 10.9.
