- fix for bug 157094
    
    A mysterious error being generated when trying to do a broadcast (sendto):
    ccsd[1704]: Unable to perform sendto: Cannot assign requested address
    
    On certain clusters (seems to be when ccs tries using IPv6), this error
    could show up 9 out of 10 times.  When the error was received, the
    broadcast attempt would fail.  This caused the attempt to grab any
    possibly updated cluster.conf files to abort.
    
    Waiting a moment, closing the socket, reopening the socket, and retrying
    the broadcast seems to solve the issue.  (It has work 100+ times so far.)
    
    I'm not entirely certain what is causing the initial try to fail - perhaps
    the underlying subsystem is not quite ready...  In any case, I have never
    seen a second attempt fail.
