That's completely missing the point of my request (which, I admit, I didn't
make clear). I need to allocate about 3/4 of available memory in the kernel.
If I had 2GB of RAM, I'd need to allocate 1.5GB. If I had 8 GB of RAM, I'd
need to allocate 6GB. I just used 3GB/4GB because it's our current test platform.
