actually post-resume scripts have been available for some time.
it was pre-suspend scripts that were added recently.

look for "Post-resume scripts" in /usr/sbin/powerd for documentation.

Note:  these scripts run when there's a high likelihood that
the system will, or did, suspend.  but the suspend may not actually
have happened.  in the case being discussed ("echo 0 > lbs_mesh"), it
sounds like that's probably okay, but you wouldn't want to use these
script hooks to implement a suspend counter, or something that breaks
the system if the suspend didn't actually take place.
