With older openssh versions, there was a problem when the stdin socket is closed before calling ssh. Newer openssh versions seem to have fixed that. So, we had a work around in Hydra for ssh to handle this case, but only for ssh. I just extended that workaround to be used for sge and rsh as well.

Sounds plausibel. But both have the same openssh (same OS, same patch 
level).
