Attempt to fit a node on a 1.7GB g1-small on GCP.
rsync basically takes like no resources to run; we hope. Most of our
real servers are doing this with like 1-2 CPUs and 2GB of memory. So
align that with our vm sizing.
The g1-small is a 1.7GB memory container with 1 shared vcpu.
Allocate 1.3GB of memory to the tmpfs. This should house 2 rsync trees
(clocking in at 590MB a piece).
Further work with hardlinks can likely reduce the size even more.
