I hadn't noticed this before, but it looks like INFINITY is not allowed
in time interval specifications, and there's no log warning about it.
:-/

Time interval specifications can be an integer number of seconds, an
ISO 8601 duration, or a number with units (s/m/h/etc.).

Timeouts are stored in milliseconds as 32-bit unsigned integers so the
limit is a bit under 50 days (though I'd keep it well below that).
