OK, these are only for shared resources like system V shared memory and
semaphores. Number of open files is controlled in a different way.

On my BSD/OS machine, sysctl allows you to control the maximum number of
open files. The sysctl manual has:

kern.maxfiles integer yes

and the 'yes' indicates it can be changed via sysctl. Perhaps NetBSD is
the same.
