Something is sure wrong in 2.1.91 mm.
I am sure all of you are developing mm stuff have 64Mbyte of ram or more since with 32Mbyte (or less) when the system begin to need a lot of memory it hang. All process running are swapped out (the same problem of 2.1.89 if I remember well, this was fixed in 2.1.90) too so there is the maximum of page_faults and all became unusable. The process that run forever is kswapd. All other process are sleeping all the time. This continued for 15 minutes and then I resetted.
Using the system after `swapoff -a` make all working very more responsive except when the memory squezee and last the procees that alloced memory is not killed (returning segfault) but the machine hang as in the case before. I proved it running `swapoff -a; startx;` and then trying to start emacs. After that I had to reset.
I suggest mm hackers to start the kernel with mem=30m or less.
