I think it does make a difference: If you remove the CANON flag  
getaddrinfo() will not do DNS lookups when the host is configured to  
prefer the hosts file (which it should do on Linux and OSX). And so the  
platform specific lookupIfLocalhost() can be put after the getaddrinfo()  
(again).

I actually think the bug "exists" on all platforms. If getaddrinfo() fails  
because neighter hosts nor DNS file finds the name this can happen on all  
platforms. I dont think it helps to add a fallback only on MACOSX (and  
there is certainly no need to prefer the fallback then).
