How to use the smmap.mman.StaticWindowMapManager function in smmap

class SlidingWindowMapManager(StaticWindowMapManager):

    """Maintains a list of ranges of mapped memory regions in one or more files and allows to easily
    obtain additional regions assuring there is no overlap.
    Once a certain memory limit is reached globally, or if there cannot be more open file handles
    which result from each mmap call, the least recently used, and currently unused mapped regions
    are unloaded automatically.

    **Note:** currently not thread-safe !

    **Note:** in the current implementation, we will automatically unload windows if we either cannot
        create more memory maps (as the open file handles limit is hit) or if we have allocated more than
        a safe amount of memory already, which would possibly cause memory allocations to fail as our address
        space is full."""
