The applications I know of that can display thread names (ps, top,
procstat) retrieve it using libprocstat and the procstat_getprocs(3)
function. The libprocstat functions access the information via /dev/kvm
or sysctl, but those interfaces return raw binary kernel data that
userland should not try to directly interpret for themselves.
