Hmm, for me it looks like that even in a single loop too much is done. A
single loop already tries to put as much as possible into the swap
cache. Two calls of swap_out_mm for the same mm in very short time and
most of the process is on swap and it will only be busy to get it pages
back.
bye, Roman
