commit    93be0950070b5bcb22600cb1cbb62f93c058a5dd
Author:   Andres Freund <andres@anarazel.de>
Date:     Thu Jan 08 12:08:05 2015 +0000

    Move comment about sun cc's __machine_rw_barrier being a full barrier.
    
    I'd accidentally written the comment besides the read barrier, instead
    of the full barrier, implementation.
    
    Noticed by Oskari Saarenmaa
