Random import failures at validation

[rth]

Currently when re-running the bundling of the same application (even a pure Python one), occasionally it would fail (e.g. with the message that some of the included packages cannot be imported)

Then work fine on the next run. This reminds me a bit of random selenium test failures, however, this is on my laptop in Node, so insufficient RAM should not be an issue.

I have worked on improving the determinism of packing, but there are likely still some issues.

For instance, maybe checking that the produced build artifact is exactly identical between two runs could be a start.

It doesn't seem to be happening anymore. Or at least without the scipy example. Closing for now. Will open a more specific issue if needed.
