It's currently set to 0, which as I'm led to believe, is the setting I
want there. But here's something interesting:

numactl --hardware

available: 2 nodes (0-1)
node 0 cpus: 0 2 4 6 8 10 12 14 16 18 20 22
node 0 size: 36853 MB
node 0 free: 13816 MB
node 1 cpus: 1 3 5 7 9 11 13 15 17 19 21 23
node 1 size: 36863 MB
node 1 free: 751 MB
node distances:
node   0   1
   0:  10  20
   1:  20  10


Looks like CPU 0 is hoarding memory. :(
