We're using nfs3 over tcp.   rsize and wsize are 32768.  Async is default,
though I've tried sync.

Funny thing is, turning on nfs debug and trying to trigger this problem
seems to cause data corruption.  Once it even managed to corrupt the local
disk writes to the points where the journals aborted and I had to reboot.
