- Simplify code
- Remove bogus leftover (tests) in the end
- Resolve deadlock that resulted from using `tcp-abandon-port' in
`net/ftp'
- Actually there's no need for threads, probably because of small size
of data, so keep it.
- Use scribble syntax instead of here-strings, and move the text out of
the way.
(It's possible to have issues with "localhost", for example when there's
something in a $LOCALDOMAIN environment variable, which made this test
fail on certain machines.)
