I personally don't see why anyone would ever remove 127.0.0.1 from their 
hosts file. This is a required entry in any UNIX environment (tru64, hp-ux, 
solaris, aix, linux) and has been that way for 30 years.

I guess this is why others haven't experienced the "bug" you've reported, as 
most people don't touch that entry - unless of cours they're asking for 
trouble :)
