   Oh right, yes it will do that sorry, been years since I wrote that code (and 
it looks like there's some new PushDecoder anyway that might change all of 
this). So yes it will behave the way you describe, which could make a 
difference for stores with high first-byte latencies. However, my understanding 
is Andrew is running on an NVMe drive where time spent doing IO will be bounded 
by bytes-read not number of fetches, which filter pushdown would if anything 
reduce...
