I've checked in your patch, with a minor alteration to die with logging 
if the pidfile can't be written.

However, I don't know of any way to make the Danga::Socket event loop 
terminate and return, and the code to clean up the pidfile doesn't run 
when the server dies in response to a TERM signal. Perhaps an END block 
would do the trick? I can't remember if END blocks still run if the 
process catches SIGTERM.
