Degradation of tests performance in release 0.2.8

[lsolovey]

I noticed significant degradation of performance in running our unit tests using 0.2.7 vs 0.2.8. The time increased from ~10 seconds to ~6 minutes.

Is anyone else seeing this as well? Why is there such a big difference?

It might be the reload of the chart under test between each test case: d55debb
I think the problem is that Helm lib is not designed to do more than one rendering (I guess it's not use case the CLI has to support), so they were nasty bugs with original cloning solution.
