Unfortunately we cannot control what the users *think* :) Many users
just try things away according to their intuition. I'd expect that
we'll have to waste more time to explain to other users trying to do
this in the near future (before it gets fixed). I already cannot
remember exactly how many times my modules' users have reported such
things in the past ;)

IMHO, if nginx cannot handle a particular case, it should complain
about it rather than hang forever. It is about usability :)

That's cool. Looking forward to that.
