    # Note that this is a trade-off: here we trade clean pages for dirty pages,
    # extra cpu and battery. That's because the quicken files will be jit-ed in all
    # the processes that load of shared apk and the code cache is not shared.
    # Some notable apps that will be affected by this are gms and chrome.
