I LOVE this messages "some process couldn't die, ps axl advised" just 
before reboot, ahem... when the box hangs somewhere in disk operations 
and only Ctrl-Alt-Del helps (with some delays).

ps just reports what kernel presents. Top displays them, too:

        zombie     0     0K      1K    36254  128

libc_r.so.5             libpthread.so.1
libc_r.so               libpthread.so

AFAIR, UPDATING recommended exactly this way. Is it obsoleted?

Nothing. Just nothing. They're absent.
