Comment 3 for bug 992110

I can confirm the findings, too. I first thought, the cause is that $AUTOSSH_FIRST_POLL does not default to $AUTOSSH_POLL from the environment, but to $AUTOSSH_POLL's default value, i.e. 600 seconds. But I couldn't confirm such a behaviour.

Unfortunately I haven't yet found the spot in the code which causes this behaviour.
