Limiting any server process to some reasonable fraction of the resources of
the machine it runs on is always a good idea.
However, NetBSD should not panic like this. When a resource runs out, the
requested operation should be refused, and the user code can deal (or not).
Basic principle: a normal user process should *never* be able to panic the
system. If it can, that's a serious bug, and it should (at minimum) be
reported as such with "send-pr".
