Implement code computing proportions of events of different type (like code in lib/proportions.c) but allowing periods to have different lengths. This allows us to have aging periods of fixed wallclock time which gives better proportion estimates given the hugely varying throughput of different devices - previous measuring of aging period by number of events has the problem that a reasonable period length for a system with low-end USB stick is not a reasonable period length for a system with high-end storage array resulting either in too slow proportion updates or too fluctuating proportion updates.
