Avoid unnecessary process wakeups in the log collector. syslogger was coded to wake up once per second whether there was anything useful to do or not. As part of our campaign to reduce the server's idle power consumption, change it to use a latch for waiting. Now, in the absence of any data to log or any signals to service, it will only wake up at the programmed logfile rotation times (if any).
