I'm going to guess it's not Cap, if the code in 'current' is correct.
Look at things which are shared, though -- I'm not sure if it's built in,
but mine shares tmp, which is used in Rails for pids and cache -- and also
log.
I would check those, and also your browser cache, especially if you're using
Firefox. Sometimes, Firefox just decides to cache things until you hit
shift+refresh.
