Mike- I thought `dispose()` was necessary with forking webservers if 
connections are made *before* the process forked, because the servers 
(typically) implement fork() behind the scenes.  uwsgi offers a @postfork 
decorator (and an explicit hook) that I use to call the dispose(), and 
gunicorn has a `post_fork` hook. i don't recall the specifics of other 
servers.
