It was necessary at the time.

The actual 1 second value was completely random - it fixed all the
issues on my test VM at the time. I don't recall exactly the details,
but I do recall having to run a lot of tests before I managed to provoke
an error, and that with the 1 sec thing i could run it for a day of
repeated restarts without any errors.
