This jails behaviour is known to cause many problems, in 
particular, it makes impossible nginx binary upgrades unless all 
listen sockets are explicitly bound to jail's IP address.

Fortunately, this was resolved several years ago by introduction 
of multi-IP jails.  You may try to use them for tests instead.

Adding quirks everywhere to support this brain-damaged "no 
127.0.0.1" case looks like a wrong way to go for me.  Especially 
given the fact that simple solution exists for years.
