Looks cool, but it's got a big warning on it saying it's not stable
for production.  Also, if the database server goes away for 5 minutes,
then instead of error 500 pages, now the website is just timing out to
the browser. That's less descriptive for the end user, when what I'm
aiming at is giving more of a "we've got a handle on things"
appearance to the errors when they happen.
