I am not sure about this yet. I will make some more research into it
and come forth with a proper answer when I have one.

Yes, you are in the wrong login class, so you cannot raise the
limit above 256M. Use the command vipw(8) to change your login class
from ''default'' to ''staff''. Login classes are defined in
/etc/login.conf with man-page login.conf(5). ''Staff'' is allowed
infinite resources with respect to data. This allows me to make a
500m fixed-heap and run it with that. With ram-slop it seems to have
a bit of problems, but I am going to find and patch that (OpenBSD likes
to avoid /proc, so I'd rather not use that if I can get away with it)
