+++ This bug was initially created as a clone of Bug #1258714 +++

Description of problem:

bug-948686.t intermittely ends up in a race in GlusterD where one thread
deletes
a stale volume and on a volume start request a start is attempted on the same  
object which might be freed up by the other thread. We are considering to use 
refcounting mechanism while accessing volinfo objects to get rid of this
problem
but that needs a significant amount of time in development. Till then adding
this test in bad_tests ()

Version-Release number of selected component (if applicable):

How reproducible:
