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.
