gearmand: Gearman client/worker connector.

OPTIONS

--daemonize / -d: Make the daemon run in the background (good for init.d scripts, bad for running under daemontools/supervise).
--port=7003 / -p 7003: Set the port number, defaults to 7003.
--pidfile=/some/dir/gearmand.pid: Write a pidfile when starting up
--debug=1: Enable debugging (currently the only debug output is when a client or worker connects).
--accept=10: Number of new connections to accept each time we see a listening socket ready. This doesn't usually need to be tuned by anyone, however in dire circumstances you may need to do it quickly.
--wakeup=3: Number of workers to wake up per job inserted into the queue. Zero (0) is a perfectly acceptable answer, and can be used if you don't care much about job latency. This would bank on the base idea of a worker checking in with the server every so often. Negative One (-1) indicates that all sleeping workers should be woken up. All other negative numbers will cause the server to throw exception and not start.
--wakeup-delay=: Time interval before waking up more workers (the value specified by --wakeup) when jobs are still in the queue. Zero (0) means go as fast as possible, but not all at the same time. Similar to -1 on --wakeup, but is more cooperative in gearmand's multitasking model. Negative One (-1) means that this event won't happe, so only the initial workers will be woken up to handle jobs in the queue.
