Comment (by yawning):

 I missed a few calls when I wrote up my list of what's required, and since
 the tor profile now has mmap rules, there's even more stuff.

 `setsockopt` -> `arg1 == SOL_SOCKET && arg2 == SO_BROADCAST`, `arg1 ==
 SOL_IPV6 && arg2 == IPV6_V6ONLY`
 `mmap` -> `arg2 == PROT_NONE && (arg3 == MAP_PRIVATE|MAP_ANONYMOUS || arg3
 == MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS)`
 `getppid: 1`
