'Karl Tremain' said previously:

I believe they are FIFO, with some caveats, as mentioned below.

I seem to recall someone mentioning that proxies prefer to hand out
partial blocks (smaller than 16*2^28) before handing out complete
blocks, so as to keep these smaller blocks from clogging the proxy.

What this implies is that the buffers are FIFO _within a given block
size_, which, over very short periods of time, could appear to behave
like a LIFO, if the blocks that are fetched are smaller than the ones
that are currently present in the proxy's buffers.

Does anyone _in the know_ care to substantiate/refute/elaborate?
