Also, when testing the change on the events structure, I think it unveils another issue. Since libaioContext is allocated on the stack and initialized by [io_queue_init](https://manpages.debian.org/jessie/libaio-dev/io_queue_init.2.en.html), calling free on it does not seem to be the correct way to perform the cleanup. I believe we should be calling [io_queue_release](https://manpages.debian.org/jessie/libaio-dev/io_queue_release.2.en.html) instead.
When using free to perform the cleanup on libaioContext, it causes this:
```

Replacing it with io_queue_release causes the test to fail with the correct behavior under failure:
