A Section needs to be added to examples seemingly not needing a Section to prevent crashing

[edovanveen]

If we remove soma = n.Section("soma"); from example_savestate it runs fine by itself. However, when combined with other example runs (for example by running all tests), not creating a Section here causes a crash:

I wonder if #47's changes to memory management fixed this.

[edovanveen]

Unfortunately, no.

[ramcdougal]

Do the previous tests involve a linear mechanism by any chance? Because we're still trying to figure out why this would be called at all.

[ramcdougal]

I wonder if we can fix this by explicitly bumping up the structure_change_count as part of the reset.

[edovanveen]

This is still not fixed, even after fixing #73
