daemon_controller is a library for starting and stopping specific
daemons programmatically in a robust, race-condition-free manner.
It's not a daemon monitoring system like God or Monit. It's also not a
library for writing daemons.
It provides the following functionality:
Starting daemons. If the daemon fails to start then an exception
will be raised. daemon_controller can even detect failures that
occur after the daemon has already daemonized.
Starting daemons is done in a race-condition-free manner. If another
process using daemon_controller is trying to start the same daemon,
then daemon_controller will guarantee serialization.
daemon_controller also raises an exception if it detects that the
daemon is already started.
Connecting to a daemon, starting it if it's not already started.
This too is done in a race-condition-free manner. If the daemon
fails to start then an exception will be raised.
Stopping daemons.
Checking whether a daemon is running.
