Administrators of large multiuser systems expect these kind of
limits to be on by default for 'ordinary users'.
Dont most vendors UNIXes have limits on by default ?
The single user workstation machine has the one power user that
can afford to get bitten once by this for the knowledge it gains
them.

"If it is true that our Universe has a zero net value for all conserved
quantities, then it may simply be a fluctuation of the vacuum of some
larger space in which our Universe is imbedded. In answer to the
question of why it happened, I offer the modest proposal that our
Universe is simply one of those things which happen from time to time."
