    clvmd: command timeout handling fix
    
    clvmd would wait for select() to time-out before processing command
    time-outs. The select timeout would be set to the cmd_timeout ('-t'
    command-line option) value, which is 60 seconds by default.
    
    Normally the select() call is woken up more frequently, so the command
    time-outs are never processed. This causes LVM tools wait forever on
    cluster locking for operations started during temporary cluster
    problems.
