created, written, drawn and then recreated upon reuse (which seems correct
behavior).

It seems, in other words, that the kernel is not keeping an extra reference to
buffers which are currently referenced by an in-flight pushbuffer, and
unreferencing them only once the GPU finished drawing.

Is the kernel already supposed to do so?
If yes, something is broken. If things work for others, maybe my system is
somehow more prone to reusing memory or GART mappings, so they don't see that?

If no, then how are things supposed to work?

(BTW, not freeing buffers leads to X freezing and the kernel oopsing on my
machine upon saturating memory, but that's another issue)
