SDB, an expert on this song and its textual roots, pointed out (during the annual gathering on the Shabbat of Sukkot) that the title comes from Kohelet 1:6:
הוֹלֵךְ אֶל-דָּרוֹם וְסוֹבֵב אֶל-צָפוֹן; סוֹבֵב סֹבֵב הוֹלֵךְ הָרוּחַ, וְעַל-סְבִיבֹתָיו שָׁב הָרוּחַ.
Goes to the south and turns to the north, turns, turns, goes the wind, and on its turnings returns the wind.
Next step: Find a source for "I swear it's not too late."
(Also, I would fully support a triennial cycle for the reading of Kohelet.)
