    Touch memory ablation payload in chunks. · 33b723f0
    dskiba authored
    It was discovered that touching (to dirty pages) large regions of
    memory can be very costly on Android (~60ms per 10MiB on Nexus 5).
    We touch on IO thread, but still, it's better not to block it for
    long periods.
    
    With this CL we'll touch the ablation payload in chunks and we'll
    schedule each touch individually to let other things to happen in
    between.
