Note that the JSON format of the `timings` messages is unstable and subject to change.
Compilation sections can be nested; for example, if you encounter the start of "foo",
then the start of "bar", then the end of "bar" and then the end of "bar", it means that the
"bar" section happened as a part of the "foo" section.
