Java classes that implements reload on SIGHUP

This minimal library is essentially a way to encapsulate the somewhat non-portable way in which a handler for the SIGHUP Unix signal can be installed. The following code

MainLoop ml = MainLoop.newInstance();
ml.installReloadHandler(onReload);
ml.run();

will install the onReload handler and then wait around until the process is told to exit by sending SIGTERM.

This library uses non-standard functionality, i.e. sun.misc.Signal, that might not be available in Java everywhere. Additionally the unit test assumes that there is a kill command that can be executed on the host system to signal the current process.
