[issue31068] [2.7] test_ttk_guionly hangs at self.tk.call('update') on AMD64 Windows8.1 Refleaks 2.7

Yesterday, I ran test_ttk_guionly during 3 hours on Windows with Python 2.7 compiled in debug mode. I saw between 4 and 7 hangs. I'm not sure about the exact number since sometimes the test unblocked when I just moved my mouse or clicked on my Command Prompt window....

At this point, I'm only sure that the following tests blocked:

* test_ttk\test_extensions.py:184: LabeledScaleTest.test_resize() -- test ttk.LabeledScale
* test_ttk\test_widgets.py:1367: TreeviewTest.test_heading_callback() -- test ttk.Treeview
* test_ttk.test_widgets.TreeviewTest.test_tag_bind() -- test ttk.Treeview

bpo-31135 fixes LabeledScale.destroy(), so it may be related.
