    T1969: Enable it again but bump the max residency temporarily
    
    T1969 was broken by 714beb (which actually reduced allocations but
    residency was increased). Instead of disabling it completely, just bump
    the number a little bit to avoid making things even worse in the
    meantime. See also #12437.
