So, MacOS X is using somewhat legacy convention from NeXTSTEP.
It seems the toplevel directory in NeXTSTEP is what modern UNIX
variants call /var.

So, if NetBSD follows what MacOS does, the per user directory must be
/tmp/$UID, because NetBSD doesn't use a symlink for /tmp.

Or, if we'd like to avoid using /tmp (I guess this is what elad wants),
a directory under /var (e.g. /var/perusertmp/$USER) seems appropriate
for me.

Unless there is concrete reason to have /private instead of /var,
I think we shouldn't introduce new toplevel hierarchy.
