After the change from revision 30103, nixos-rebuild suddenly consumed freaky amounts of memory. I had to abort the process after it had allocated well in excess of 30GB(!) of RAM. I'm not sure what is causing this behavior, but undoing that assignment fixes the problem. The other two commits needed to be revoked, too, because they depend on 30103. svn path=/nixos/trunk/; revision=30127
