  We consider profinite groups in which all commutators are contained in a
union of finitely many procyclic subgroups. It is shown that if G is a
profinite group in which all commutators are covered by m procyclic subgroups,
then G possesses a finite characteristic subgroup M contained in G' such that
the order of M is m-bounded and G'/M is procyclic. If G is a pro-p group such
that all commutators in G are covered by m procyclic subgroups, then G' is
either finite of m-bounded order or procyclic.
