I imagined a constant static block before, but gave up due to concerns about 
p_next or other block_t fields being potentially modified. Storing the flush 
block per decoder is an innovative trick to partly alleviates the problem. I 
am not certain that there are no corner cases where the block would end up 
being used more than once concurrently still.

I think we would be better off with explicit flush callbacks.
