See above. The columns further to the right are debugging info.

I'd definately like to see this. It would be great if somebody would sit down and implement this. <hint> <hint>

This isn't currently possible. Also, I suspect what we really want for most situations is a way to better balance between the different uses of memory. Again, patches are welcome (I haven't figured out a way to take care of this balancing yet ... maybe we DO want some way of limiting memory usage of each subsystem??).
