I found the leak. As predicted, it was stupid, a get_page left over from a
previous incarnation. Now it's behaving pretty nicely. I haven't seen an
oops for a while and leaks seem to be down to a dull roar if not entirely
gone. I think swapoff isn't entirely comfortable with the new situation, and
tends to hang, I'll look into that in due course.
Since I don't actually have a user base for this, I just overwrote the
previously posted leaky version, it's still:
nl.linux.org/~phillips/ptab-2.4.17-3
This is getting to the point of needing heavier testing.
