Yet another MM problem (kswapd-zombie)

[Zlatko Calusic <Zlatko.Calusic@CARNet.hr>]

I almost forgot, there is yet another big problem with changes on
kswapd (in pre5). Now, that kswapd is killable, in fact it only
becomes zombie, when SIGKILL is sent to it.

And not only that. If I run 'init 1' to go temporary to single user
mode, killall script zombifies kswapd (without asking me). If I later
return to multiuser level (plain ctrl-D), kswapd cannot be started
again. Or at least I didn't come up with a solution. I think that is
bad thing to happen.

If kswapd has to be killable (is it really necessary?), than we should
not lost it by simple changing runlevels (people do that, trust me).

Any clues?
