This article is somewhat misguided. Limiting the number of user processes
is an excellent idea, but provides no protection against a knowledgeable
hostile user. If one of your users wishes to make your service
unusable by hogging some resource then they will certainly find a way of
doing it. The solution is to take away their account.

Fortunately legitimate users very rarely wish to make the service
unusable. However, they may very well *accidentally* run a fork bomb (I
have done it myself) and for this reason it would be friendly of SuSE to
ensure that default setups always set a process limit (it doesn't have to
be very small).
