Are you aware that the contents of /etc/hosts get loaded into _every_
process doing hostname resolution? And the file isn't mmap'd in and so
shared, but is instead _read_ into each process, so is not shared
memory?
Seriously, install unbound, use unbound-control and/or home-grown tools
to maintain the list of overrides, make sure the cost of filtering is
only borne once, instead of having zsh also load a 4MB hosts file and
parse it out. Your system will be faster for _every_ hostname-resolving
package, not just zsh.
Otherwise, use zstyle to set 'hosts':
zstyle ':completion:*:hosts' hosts $the_hosts_you_care_about
and so override the automatic parsing of /etc/hosts.
