There's been talk of such things (OS X has a similar scalable mixed kernel/user-space notification service that it uses for things like indexing), and it absolutely should be created for Linux -- but TALPA has requirements well beyond that. Blocking read(2) until some other userspace process has woken up and okay'ed things is *way* outside the scope of an inotify-alike!

inotify?

Actually it's not so far away from inotify.

We have leases in fcntl() F_SETLEASE, they go alongside dnotify in fcntl() F_NOTIFY.

inotify could similarly benefit from an an ilease extension, as well as further scalability improvements. (inotify was designed to improve on dnotify in many ways including scalability; it's a shame it stopped half way).

That's blocking readers right there.
