Much belated, this attempts to address the concerns about deadlocking.
Basically, this says that you should avoid instructions that don&#39;t have
flow control credit.  It doesn&#39;t say how an encoder might learn what
limits are, but we&#39;ve seen a range of tactics being used in
implementations and I don&#39;t want to get into transport API debates.

This doesn&#39;t cover the memory exhaustion attack that @kazuho suggests on
the issue; I think that is better covered more generally by the
connection-level flow control limits.

Closes #1420.
