Panic on slow network (introduced in api/v0.6.7)

[larsha]

I'm getting a panic in the kustomize-controller. It looks like it was introduced in api/v0.6.7.

panic: send on closed channel

goroutine 537 [running]:
sigs.k8s.io/kustomize/api/loader.getRemoteTarget.func1(0x4000704210, 0x4002ecfe60, 0x40028a0150)

Here is an issue tracking this: kubernetes-sigs/kustomize#3362
