It is probably worth revisiting MAXUSERS.
After all the default (16 or 64?) is just enough for one person.

IIRC a lot of limits are based on it, most of which probably
predate the dynamic allocation of the relevant structures.
Limits for the total number of open files and processes (etc)
are probably better based on system memory size (or even
available memory/kva/swap).

I remember a fixed size hash table for uids that could be done
a better way, but everything else just set soft limits.
