The personal proxy has always been modified FIFO. Client is technically
a modified LIFO (its buffer format is LIFO, but it makes efforts to
extract blocks in order according to their keynumber). Since we assign
blocks in a generally linear distribution, the effective order from the
client is generally FIFO.

I was certain this was documented somewhere but I cannot find it. I
think last time the topic came up it was said that the client works on
the lowest numbered block first. So for the most part it should be FIFO.
