fcntl on struct file was deemed too intrusive - as far as fds are
concerned, regular files and pipes have names and local processes to
match against anyway
we're left with mostly remote targets - one example was to preserve
target host names after resolution (alas, I don't think there's a
clean flow to hook that transparently)
