No, I actually was able to reproduce your result without using syslogd:
$ setsid sleep 10 >/dev/null 2>&1 </dev/null
(shell prints "logout", but window remains until sleep is over).
In fact, closing the file descriptors doesn't work either:
$ setsid sleep 10 >&- 2>&- <&-
I've generated the strace for the above cases, and will take a deeper look
when time permits.
