def bigmemtest(minsize, memuse, overhead=(5 * _1M)):

    ''''Decorator for bigmem tests.
    \'minsize\' is the minimum useful size for the test (in arbitrary,
    test-interpreted units.) \'memuse\' is the number of \'bytes per size\' for
    the test, or a good estimate of it. \'overhead\' specifies fixed overhead,
    independent of the testsize, and defaults to 5Mb.
    The decorator tries to guess a good value for \'size\' and passes it to
    the decorated test function. If minsize * memuse is more than the
    allowed memory use (as defined by max_memuse), the test is skipped.
    Otherwise, minsize is adjusted upward to use up to max_memuse.'
