proc_walk(3PROC) skips SSYS processes, so it never descends into children of zsched, preventing -z from working.
Built new binary + libproc, ran new (and pre-11096 binary of ptree), and compared output -- aside from the pid of the ptree processes themselves, no differences were found.
Then ran both pre-11096 + new binary with -z argument of a running zone and compared output. The output was identical
