self-heal tests

[Gerry Reno <greno@xxxxxxxxxxx>]

Do not know what the test plan looks like for self-heal but I would like 
to suggest that reboot tests be made for 1.4 and self-heal.  The ability 
to survive a spurious production server reboot and have all cluster 
nodes recover fully is one test that would be critical.   Whether 
unplanned, like kernel oops and crashes, or planned, like server 
maintenance or recovering a hung process, reboots happen all the time 
and it will be critical for GlusterFS to fully survive reboots and heal 
without manual intervention.

Regards,
Gerry
