newfs limits? 10TB filesystem max?

I've just built an enormous 10TB filesystem.  When trying to newfs the disk, it bombed with something like "cannot allocate memory" after something like 23xxxxxxxxx sectors..  I noticed disklabel complains about disks with more than 2^32-1 sectors not being supported..  

Is newfs supposed to be able to work?  I've used the -s option to newfs to limit my filesystem size to the max it would allow, which ends up being 11350482546 1K blocks, which means I'm only losing a couple GB, which is no sweat right now for me, but if someone wanted a 20TB filesystem, they'd be hosed.

Also - what are the newfs implictions?  I have 1GB of RAM, is that enough?

I'm running 5.3-STABLE on this box right now..
