Inside the trace end function the final output will be dumped
to standard output in JSON gecko format. Additionally, constants
such as USER_CATEGORY_INDEX, KERNEL_CATEGORY_INDEX, CATEGORIES, and
PRODUCT are defined to provide contextual information.
Also added _addThreadSample call which was missing.
