BTW, another interesting test might be reproducing the problem with the
X server manually, such that it won't terminate but just reset when the
last client goes away. Is the memory reclaimed in that case as well?

Not sure where you're going with this... It seems clear from your
previous posts that the memory is accounted as kernel memory. The
question is what is causing that memory to be allocated and only freed
when X dies.
