A tangential FYI: the Debian packaging will be taking care of this as part
of the installation.  Currently it installs the
/etc/security/limits.d/squeak.conf file and I'll look into adding the pam.d
part as well.

Of course if there's a way to get the functionality without the config
tweaking, that would be even better.  If not, well that's one of the many
reasons we have packages ;-)
