+* WONTFIX: code reloading and restarts with Sinatra 0.3.x (and likely older
+  versions) apps is broken.  The workaround is to force production
+  mode to disable code reloading as well as disabling "run" in your
+  Sinatra application:
+    set :env, :production
+    set :run, false
+  Since this is no longer an issue with Sinatra 0.9.x apps, this will not be
+  fixed on our end.  Since Unicorn is itself the application launcher, the
+  at_exit handler used in old Sinatra always caused Mongrel to be launched
+  whenever a Unicorn worker was about to exit.
+
+  Also remember we're capable of replacing the running binary without dropping
+  any connections regardless of framework :)
