    SUPPORT.md: limit security support for hosts with very much memory
    
    Sufficient and in particular regular testing on very large hosts cannot
    currently be guaranteed. Anyone wanting us to support larger hosts is
    free to propose so, but will need to supply not only test results, but
    also a test plan.
    
    This is a follow-up to XSA-385.
