No, I actually was able to reproduce your result without using syslogd:

$ setsid sleep 10 >/dev/null 2>&1 </dev/null
$ exit

(shell prints "logout", but window remains until sleep is over).

In fact, closing the file descriptors doesn't work either:

$ setsid sleep 10 >&- 2>&- <&-
$ exit

(same result).
I've generated the strace for the above cases, and will take a deeper look
when time permits.
