Not that 4 VMs were being provisioned at approximately the same time (only one
per call to \{{createNodesInGroup}}).
We should guard against
\{{org.jclouds.googlecomputeengine.compute.functions.Resources.disk(key)}}
returning null when called in \{{DiskURIToImage.load(key)}}. The load method
returns an \{{Optional<Image>}} anyway, so should be easy to change.
