008 and 056 can pass on my environment.  Are these not false alarms?
I occasionaly see the following errors and sheep fails to start up
with the zk driver.

  zk_join(799) Previous zookeeper session exist, shoot myself.

069 fails on my environment too, but it fails even after I reverted
this patch.  Maybe, my previous series to clean up group.c would be
the root cause.

Thanks,
