--- Comment #1 from Damien Miller <djm at mindrot.org> ---
I'm not sure how I missed this report at the time, but this bug is
reproducible.

The problem seems to be tty related and adding

+       ssh_signal(SIGTTIN, SIG_IGN);
+       ssh_signal(SIGTTOU, SIG_IGN);

to ssh.c makes it a little better: the 2nd window no longer hangs but
the first one still does.
