 In the bandwidth file, sbws should report how long it takes to measure
 (almost all) the entire network.

 Here's one way we could work out the network measurement "half-life":
 1. Count the number of relays in the network, N
 2. Find the last N/2 successful, unique relay measurements
 3. Report how much time has elapsed since the earliest measurement in the
 list
 (We use the half-life, so that failed measurements don't affect the final
 time too much.)

 We could monitor this figure for each scanner, to make sure they are
 working correctly.
