I'm not sure about this theory. The normal case will be that all
allocations (maybe one or two order 1 or order 2 allocations if I've
forgotten something) are order 0 and processes are thawed after we've
freed all the memory we were using. Could that still trigger kswapd?

I'm flying to America on Monday, but I'll try to keep up with the
progress in this and do anything I can to help.
