Gleb. How about using MADV_SEQUENTIAL on guest memory?
It makes that pages of guest are moved into inactive reclaim list more
fast. It means it is likely to swap out faster than other pages if it
isn't hit during inactive list.

Yeah, something like that but we don't want the readahead. OTOH, it's
not clear what Gleb's real problem is. Are the guest address spaces
anonymous or file backed? Which parts of the emulator are swapped out
that are causing the problem? Maybe it's a VM balancing issue that
mlock papers over?
