Sometimes a sock file stays there after I stop puma. Well actually most of the time it stays there, at least on JRuby for me. Then when I try to start I get

 ** [out :: 88.] * Listening on unix:///home/x/shared/sockets/puma.sock
 ** [out :: 88.]
*** [err :: 88.] IOError: Connection refused

I have to manually delete the sock file (which is doing nothing) so that I can start puma. Is it not possible to handle this case and remove the sock file if it's not being used? It is really annoying.
