    Yep, NFSv2 works, but it creeps along very slowly.  A dd never
seems to climb above about 400K/sec on a P100, regardless of the block
size.  I notice a lot of hard drive chatter during any sustained write
operation.  Anyway, I don't actually need loopback NFS mounts... it
was something I tried when tracking down another problem.

    Is it specifically a problem with the lo interface?  Can it be
avoided by somehow going through an Ethernet driver?
