vm kills processes in our 2.3.12 port of reiserfs - what was the story

We have a port of reiserfs to 2.3.12 in which dbench suffers from processes
getting killed
due to not being able to get memory. There were some changes to
mark_buffer_dirty() in the 2.2
series that got dropped from the 2.3 series. The 2.2 version as I remember was
intended to prevent
this very problem. What is the story on this? This problem doesn't happen
with ext2 with the same
number of clients, but I don't know how much that means. Does ext2 do something
now to avoid
the issue?
Finally, let me ask the dumb question: why does vm do this, why doesn't it stall
rather than kill the process?

Get Linux (http://www.kernel.org) plus ReiserFS
(http://devlinux.org/namesys). If you sell an OS or
internet appliance, buy a port of ReiserFS! If you
need customizations and industrial grade support, we sell them.
