Description of problem:

   Problem:
    https://build.gluster.org/job/centos7-regression/7337/consoleFull
    indicates the shd crashing for this .t. On looking at the core, I see
    the crash is at the time of shd init and glusterfs context is null:

    (gdb) bt
    (gdb) p ctx
    $2 = (glusterfs_ctx_t *) 0xf00000000

    The .t is killing all gluster processes immediately after volume start,
    so it looks like a race between shd coming up and it being killed.
