Python API: Missing locking of results data structure.
The wrong assumption that the GIL combined with CPython's "mostly" thread safe assurance does not hold. The combination of a slow event handler for notification and calling the API at the same time let to contention on the results data structure. Added suitable locking. Also added an atexit() to attempt a VPP disconnect on shutdown. Also: lots more comments, docstrings, duplicated code removed. Some of the problem here was a disagreement between caller and author as to how the API should be used; the comments should help.
