Jason, There's just no getting around the fact that the Xserver is going to consume memory. And for the most part, it's not X's fault, it's the applications. the Xserver allocates memory on the apps behalf, and most apps don't tell the Xserver to release the memory when it is done with it.
So, for now, we have the NFS-Swap safety net, which is better than having the Xserver croak.
