[discussion of pagedaemon having a tight loop when kmem is low but trying to free some isn't successful]
http://mail-index.netbsd.org/tech-kern/2013/03/04/msg015063.html Lars has adjusted the default maxvnodes, which should help most people From avoiding the pagedaemon tight loop. But I think it still makes sense to apply Richard's patch, which should make the truly-out-of-memory situation behave a bit better, with many processes stuck waiting for memory, rather than the system locked up. It will remain to have more (and more effective) drain routines, and perhasp an out-of-memory killer. So if there are no objections, I'll commit Richard's patch (in the message linked above).
