Comments on decisions:

  • Placed reentrant lock logic directly into Tkinter 'cuz reentrant locks aren't used anywhere else, and this is easier than overhauling all 4 PyThread lock implementations. (They're also based on condition variables which don't support reentrance.)
  • Pushed both fixes to the same PR 'cuz the test case based on TkinterHanders3.py detects both bugs and would fail CI otherwise
  • Reentry count overflow check can probably be replaced by an assert: unless there's a bug, we'll sooner hit RecursionError or MemoryError.

Test case has code nonportable to Py2. Shall I make it portable or compose a backport by hand?
