I got a few queries on this comment already..
The thing is that kswapd should notice so quickly these days that the machine is low on memory that it normally really shouldn't matter what we do in "try_to_free_pages()", so even the above complete breakage might no thave all that much of a negative impact on real-life situations.
As it stands, 2.1.116 definitely will have some really bad behaviour when you run out of swap, and I suspect it has fp problems too. I was just so happy that I no longer could crash it that I didn't look through the patches as carefully as I usually do (I found the breakage later on when I actually _did_ do my normal "let's check the patches out" thing).
