    _______________________________________________________

Details:

although timeouts are relative to timeouts_last_time (transitively by
addition to the time values of their predecessors, if there are any),
sys_timeout does not compensate for that; as a result, timeouts fire too
early unless invoked from within a timeout handler (when
timeouts_last_time == now).

note on interaction with patch #7855: i think the relative timestamp approach
is sound by itself and more straightforward, it just needs to be fixed (with
the presented patch).
