Comment (by Lingxi Li <lilingxi.cs@…>):

 In other words, when process exits unexpectedly, it is not guaranteed that
 locks owned by it with kernel of file-system persistence are released, at
 least on Windows platforms. This could lead to very serious problems. For
 example, suppose multiple processes are putting log records to a viewer
 process using an interprocess::message_queue. When any process, be it a
 logger or the viewer, crashes, all processes involved may just be
 deadlocked.
