> the test is done only once with a small size (5147)
How do you run the test? Do you specify a maximum available size?
If you run test_bigmem.py directly, try to run it with an additional
argument like this:
    ./test_bigmem.py 7G
If you run regrtest.py, you should add an option like "-M 7G".
(assuming you have enough RAM...)
