The mimalloc in PS5MC (PPSA99420) reads vm.overcommit at start-up and
stopped on the unsupported name. It reports FreeBSD's default, 0.

The dolphin_libretro core of RetroArch (PPSA99169) reads {CTL_HW,
HW_REALMEM} as the machine's memory size and stopped on the unsupported
MIB. It reports the same value as hw.physmem.

FreeBSD sysctl_find_oid returns ENOTDIR when the MIB continues below a leaf object. The supported hw.ncpu, hw.model, hw.physmem and kern.arandom MIBs threw an unsupported MIB error instead.
(cherry picked from commit 6968aea8af578c4d56dc614cbe449274bb6e76e7)
FreeBSD sysctl_root rejects a write to a read-only node with EPERM before the node handler checks the MIB length, so a write with a short or long kern.proc.pathname MIB fails with EPERM. sysctlbyname for kern.proc.pathname now goes through sysctl with its 3-component MIB so it follows the same order.
The Python in PS5MC (PPSA99420) reads sysconf(_SC_CLK_TCK) while
importing its posix module and failed with "cannot read
ticks_per_second". It returns FreeBSD's CLK_TCK, 128.

ScreenTester5 (PPSA69420) stops at start-up on the unresolved sysctlbyname
import and also imports sysctl. hw.ncpu (CTL_HW.HW_NCPU) reports the same
processor count as sysconf(_SC_NPROCESSORS_ONLN). Other names and MIBs throw.
