[LRUG] Making Rails time out

[Mr Jaba]

This looks like a potential solution:

Return a special status code to Nginx which will then silently drop the
connection. I think with Rails it will always want to return some kind of
response unless you do the sleep, so you might have to do this at the web
server level.
