commit 35699ef9f5d2814203653e16cb0cd176a0190ae0

    Drop the MaxMemInCellQueues lower limit down to 256 MB.
    
    on #9686, gmorehose reports that the 500 MB lower limit is too high
    for raspberry pi users.
    
    This is a backport of 647248729fa65f0e51d062e2af8f4e8b38592bf5 to 0.2.4.
    
    Note that in 0.2.4, the option is called MaxMemInCellQueues.
