2450c450ab telnetd: at Alexander Kriegisch <Alexander@kriegisch.name> insistence 
add an option to close sessions as soon as child exits.
Maybe it should be a CONFIG option. OTOH, maybe it should be always on,
as it mimics, say, getty's behaviour.

10916c5c6b telnetd: document bug in remove_iacs. reinstate band-aid 
which was making it near-impossible to trigger.
remove memmove call which was happening at each network read,
and in 99%+ cases was not needed. Unfortunately, +50 bytes.

4f95e5aab8 vi: don't wait 50 ms before reading ESC sequences 
inetd,syslogd: use safe_read instead of open-coded EINTR handling
syslogd: bail out if you see null read from Unix socket
(should never happen, but if it does, spinning forever
and eating 100% CPU is not a good idea)
