qvm-run returns 0 even if DVM fails to start

[v6ak]

Qubes OS version:

3.2

---

Steps to reproduce the behavior:

Run this script: https://gist.github.com/v6ak/81dcab48400d24ea636f630a6a693b76

Expected behavior:

It starts new VMs until there is not enough memory. Once a VM start fails, qvm-run returns non-zero code, failing recursively all the script instances across the VMs.

Actual behavior:

When OOM point is reached, qvm-run returns 0. See the output in the gist.
