    Note ABI of XResQueryClientIds
    
    XResQueryClientIds is now documented to return an array of 32-bit
    values, not an array of longs. The previous implementation allocated
    space for 32-bit values but read longs into that, overflowing the
    array. Applications using this were expecting 32-bit values.
    
    This "worked" on little endian 64-bit systems because only one value
    was typically provided and the low 32-bits got stuck in the right
    place, although the allocation was overrun at the end. That might
    cause trouble if the allocator is checking carefully.
