FAIL in test_leaks2, test_leaks3

[cfarrow]

The test leaks tests fail under 64-bit python.

I'm still seeing this in the PR builder. Reopening.

Those tests are skipped(see #267 and #297).
Bringing back those tests has a different problem than other environment-dependent tests.

We should make this will be related to the issue of memory leaks and their testing.

So, I will leave this issue Open.

It would be good if you clarified that GUIDs in this snippet should be completely different by alternating characters. E.g., instead of three xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx it'd be good to have xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy and zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz.

Of course, there's a sentence below the snippet that states that GUID must be unique ("separate"), but IMO it wouldn't hurt to clarify this in snippet itself.
