On one of my boxes, the xenstore-write setting dom0's name starts before xenstored is actually ready to handle the connection properly, resulting in the name set failing. Wait for xenstored to be up and responding to reads before continuing, timing out after 30 seconds. Signed-off-by: George Dunlap <george.dunlap@eu.citrix.com>
