I'm less concerned about NUMA configurations... I agree that
NUMA support could be added later.  My first concern would
be discontiguous memory as, on ia64, it is not uncommon
for a machine to have a physical memory map of something like:

0GB-1GB
2GB-4GB
64GB-69GB
Total  8GB

How does the Rusty Russell allocator handle a map like this?
