I know that you folks have taken a different turn with this
discussion, but I need to post my test results to finish what we
started a couple days ago, for other readers.
RESULTS
In Tiger, it behaves as I recall and exactly as Kanny described: The
timeout gets rounded up 30 or 60 seconds. Bug.
In Leopard, the timeout works correctly, even down to 1 second. Bug
has been fixed.
