My confusion.  IBURST for the Initial loading of the buffer.  BURST for the
very, very infrequent connection to reload the entire buffer each time.

But what about the idea that IBURST is nice for fast startup, BURST is
helpful if there hasn't been a poll for a very, very long time, and now the
new idea for an explorer packet (only one extra) that would be nice to
smooth the network path when the polling interval goes over a couple of

It turns each of them into virtually the same case, classified by when the
polling interval currently in effect.
