Probably also raise the soft limit of #files, and setting all the
hard limits to fixed values.
Currently a lot of the hard limits match system limits - many of
which are local-user DoS attacks.

Remember any user can set the soft limit to match the 'hard' limit,
root can increase the hard limit as well.
The current 'default' values don't seem to have been set with that
knowledge.

Some of the current system limits that set the hard limits (like
the number of file structures) should probably be abolished completely.
It might make sense to reject non-root attempts to create some items
when memory is low - but otherwise they make little sense.
