We find a limit cycle in a quasiequilibrium model of evaporative cooling of a two-component trapped fermion gas. The existence of such a limit cycle represents an obstruction to reaching the quantum ground state evaporatively. We show that evaporatively \ensuremathβ\ensuremathμ\ensuremath∼O(1). We speculate that one may be able to cool an atomic Fermi gas further by photoassociating dimers near the bottom of the Fermi sea.
