You don't seem to be using ssh2, but I say this anyway as a FYI to
anyone that might have the same problem (or if you, gawd forbid, would
like to try our client out !-) ), fiddling with either "-f" ("fork to
background immediately after authentication") or "-S" ("don't request
a session channel" (mind you, ssh-2.3.0 a bug in "-S", which is fixed
with 2.4.0)). "-f" implies "-S".
In a script you probably want to use "-S", as then you know when the
ssh2 process really finishes.
