"kill 0" should be appended to the original script in order to kill all
child processes. Otherwise the connection won't close right away because the
socket is still open in the subshell, even if the parent has already died.
You could close it with "exec <&- >&- 2>&-" and get the same result, but
that leaves orphant processes behind -- blech.
Corrected script:
#!/bin/sh
TIMEOUT=60 # seconds
NEWPOP=pop.example.com
me=$$
( sleep $TIMEOUT ; kill $me ) &
echo "+OK FAKEPOP"
read user
echo "+OK Password required"
read password
echo "-ERR Please use $NEWPOP instead"
kill 0 # kill all childs
