Continuing the saga of testing this patch, some more things:
* Swap gets *really* filled up. I don't remember having swap totally
filled with 2.2. and this has 20M more (doesn't have to do with this
patch, I think)
* kernel appears to try to free pages only when they are desperatly
needed, i.e., when swap is full and a big process is needing mem. As an
example, i was calm editing some text files (swap was full), and called
javac. System went down to his knees, music stopped, mouse had repent
stops and javac outputed:"Killed". I assume it was killed :-)
javac was called again and then ran more smootly. Perhaps because his
pages were already there, no?
It may be better to try to free pages before we get into heavy load. If
not, we get a pseudo-freeze and a killed process. Wich is not... wonderful.
