    [2836-2] use managed_mapped_file to cause remap at different addr.
    
    the original setup was not really portable and quite dangerous, making
    a very large file.

    [2836-2] make sure remapping boost segment even if grow() fails.
    
    otherwise, subsequent cleanup to be exception safe will cause a crash.
    and, if the remap fails simply abort(); there's no hope to recover from
    this situation reasonably.  and clarify in shrinkToFit() why it behaves
    differently.

    [2836-2] make sure flush()ing the base segment before grow/shrink
    
    I was confused at the time I removed it in #2831.  these were actually
    necessary.
