W.r.t. the use of AI_CANONNAME, this doesn't actually make a difference in the context of this fix, but is definitely something that should be looked at. I'll put it on the todo list.
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).
