Yes, I'm aware of this, but I don't want to have to depend on the config file.

OK thanks, I guess I could use '-o ControlPersist no' or run another ssh process with '-O exit' after running the rsync commands.
However, I'm still interested to know if there is a more general way of killing long-running child processes. Seems to me that this is quite a fundamentally important ability.
