It does if you leave calc with `calc-quit' ("q" or "M-# x"), that is;
'calc-quit' explicitly removes the calc-undo history.
If you change buffers or bury the Calc buffer some other way and then
reenter it, then the undo history will still be there.
Does the calc-undo history disappear without quitting Calc?
