For once, we'd have a stable API for something on Linux, though ;)
Has anyone asked about relaxing the GPL restrictions on those
interfaces? I know such discussions probably almost always go nowhere,
but these interfaces are emulatable from _userspace_... I mean, come on.
And also, to be clear: I was just wondering about the technical details.
I'm pretty sure I wouldn't even use this functionality if we had it, and
I haven't heard a lot of clamoring for it (the search indexing project I
consider to be separate).
