Well, on an 8GB box doing a "mtest -m1000 -r0 -w12" (ie. create 1GB
heap and fork off 12 writer sub-processes touching the heap at random),
I get a complete lockup just after the system goes into swap. At one
point I was able to capture an EIP trace showing the kernel looping in
stext_lock and try_to_swap_out.
