    kill -9
    deferred close via mmap
    etc etc etc

    You can't just armwave it into glibc, that doesn't hold water. You also
    have shared state between processes (index on last close of a handle
    shared by several threads or processes).

    Same problem you have in the indexing business (which also wants the
    close hook) - aside from all the practical issues that LD_PRELOAD tends
    to turn up.

    I'm not actually interested in the AV stuff, but content indexing I do
    care about and we do need a way to get notification up to user space.
