  icomment: Sorry my bad, I should have given a bit more context. This is
            happening with the tk update command after simply adding a few widgets
            to the window. I have attached a simple wish app that adds some random
            widgets and times the update idletasks command each time. When I run
            this with version 8.6.17 I get the following output after adding 5
            random widgets.

            First update idletasks: 3  update idletasks ->> After adding TLabel
            widget ->> 38  update idletasks ->> After adding TCheckbutton widget
            ->> 100  update idletasks ->> After adding TProgressbar widget ->> 38
            update idletasks ->> After adding TCheckbutton widget ->> 13  update
            idletasks ->> After adding TRadiobutton widget ->> 33

            However when I run it with version 9.0.2 and do the same I get the
            following:

            First update idletasks: 2  update idletasks ->> After adding TEntry
            widget ->> 5  update idletasks ->> After adding TProgressbar widget
            ->> 32496  update idletasks ->> After adding TLabel widget ->> 22307
            update idletasks ->> After adding Text widget ->> 22224  update
            idletasks ->> After adding TEntry widget ->> 23850

            Let me know if you would maybe prefer for me to copy and paste here
            the raw code that I have in "update_bench.tcl" for security reasons.
