ssh client verbose session

ssh hangs when -t option is used to force pseudo-tty allocation to
execute a command remotely. It hangs just after 'debug1: channel 0:
open confirm rwindow 0 rmax 32768'. This has been reproduced using
multiple accounts on multiple client OS ( Solaris/AIX/Linux with
varying client versions ) to rule out problem with client. Not all
servers with the same version of OpenSSH are affected though, but the
configurations are the same across working and non-working servers.
Nothing more is logged on the server other than a successful
authentication/login.
