This is a cutdown slightly changed testcase for a performance problem
I'm having in a real program. I'm using some tabs that recreate their
contents in my program, because their contents depend on values input
by the user from another tab. In the testcase, imagine that the first
tab is not blank but lets you specify the number of rows and columns
of the table of buttons on tab 2.
