I'm very sorry to have taken so long to reply.  I don't
check this box very often and I am deep into development so
checking it even less.  I'll check back tomorrow for a
reply.

I can add a remove method and test cases unless it's easier
for you to just add it.  I think it would just use the
remove method on the Collection.  If the iterator returned
by the Collection implementer doesn't support it then this
won't either.

As for a use-case, I am using it for a displaying a number
of our banner ads on our e-commerce site.  The round-robin
task dispatcher mentioned earlier is another one.
