OK, so it was userdirs... You can relatively easily stop this happening
for most contexts by copying the _users function to somewhere earlier in
your $fpath and commenting out the last line.  You can still have
a list of specific users you want to complete, but it won't query the
system.  (If you have permission you can doctor _users in place, of course.)

There are still other places that use userdirs.  One is the _expand
completer.  If you use that you can do a similar trick by commenting
out the complete expression in braces:

  { [[ ( "$word" = \~* && ${#userdirs[(I)${word[2,-1]}*]}+${#nameddirs[(I)${word
[2,-1]}*]} -gt 1 ) ||
       ( "$word" = *\$[a-zA-Z0-9_]## && 
         ${#parameters[(I)${word##*\$}*]} -ne 1 ) ]] && continue=1 }

You can decide if you need to worry about _tilde_files.

I can see uses for a feature to override special parameters like
userdirs selectively.  Unfortunately the current state of the parameter
code makes implementing this very hairy.
