I hadn't actually. I simply started at the oldest pending thing, and
reviewed it.

Ah, good catch. I'll return a null object instead.

This object will fail in the method call, and log an error. It shouldn't
segv though, and we won't be introducing a null object check that
doesn't need to exist.

I'm checking in the current code, as I refactored to make some things
clearer before I introduced the NULL object.

Attached is my test program for this..
