    tests: Don't run memory-exhausting tests by default
    
    These tests check for memory overflow in various internal
    allocations, and require giant amounts of address space.
    In continuous' vm, they trigger the oom killer. Since this
    is undesirable, only run the tests in slow mode (ie with -m slow).
