Entries in the hosts file are only used when opening connections, via
inetd, they have no effect in the tcp stack, only a slight delay is added
to the startup of an application ...

(There are sometimes subtle side effects to this tho, eg if someone
attacks your machine by opening lots and lots of inbound connections, then
having a lot of entries will slow it's response down, but we're talking
hundreds, not dozens, they are only 4 bytes each ;)
