> 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.
