It gives lesser breakage here:
- with an old PCI em, an error that occur every few makeworlds over nfs now
   hang the hardware.  It used to be recovered from afger about 10 seconds.
   This only happened once.  I then applied my old fix which ignores the
   error better so as to recover from it immediately.  This seems to work as
   before.
- with a newer PCI-e em, throughput as measured by netblast is down by
   more that a factor of 2 since last month.
