The iterator would stop when None was read, so that's implicit.  Again, this
idea assumes a producer/consumer model rather than the repeated calling
model that is supported now.  And that, of course, implies some kind of
thread or fork and communication through a pipe or some other form of IPC,
unless there's some aspect of the apache API that I'm not aware of (which is
highly possible :)

That may be a code path you don't want to take, but I thought I'd throw the
idea out there anyway.  And there may be a way to implement this that isn't
as complex as I think it might be.
