openssh unix dev - Oct 2001 - sshd fails to close open file descriptors when forking

I don't like to be the bearer of bad news, but...

In light of the big "ssh hangs on logout" thread (wherein the true
culprit was identified as being programs that don't close inherited
file descriptors), I find it somewhat ironic that one of those "broken
daemon" programs that doesn't close its open fds is sshd.  :(

(At least it shouldn't be too difficult to fix...)

So how exactly does sshd exit without closing it's (inherited or other)
file descriptors?
