Yeah, there was a problem with *extreme* sharing ... the code tried to 
use the same buffer for multiple disk blocks at the same time, and 
somehow the backends did not agree on the correct content. But it's 
fixed and back in. You can see ARC working by setting
    buffer_strategy_status_interval = 10 # seconds

and starting postmaster with -d1
