No. This is a new thing and this wasnt there before. In 2.6.10-rc2 the kernel aborted programs with 
"Out of memory" when too many buffers are allocated and low memory was full. NOW it just shrinks the 
buffers dynamically. I don't want that. I have a 2/2 system and I want 1600 MB for buffers but you 
only allow around 700 MB for buffers. This is definetly NEW.
