Equeue is rewriten extending SocketServer.ThreadingUnixStreamServer (Thanks to Julien M.).
So far outputs of commands invoked by equeue are redirected to /dev/null to avoid locking the whole process.

equeue: Fix identation problem

The server listen on an unix socket and wait for a json request which
look like :
  {"command": "/command/to/run",
   "timestamp": 0}

The server respond sending back the command it will run.

The server is single threaded on run each command only one by one.

If one command requested two times with the same time stamp, it
will be runned only once.
