Bump up NFS wait time in qdo (since this has been causing

problems in pool regressions).

util/qdo:
    Bump up hardcoded NFS wait time from 45 sec to 90 sec (and
    print threshold from 10 sec to 30 sec).  Would be even
    nicer to make these cmd-line params, but nobody would use
    them anyway.
