Apart from the issue with 'posting' the events immediately, this seems fixed now.

I started over from scratch (rather, from the example code that -somewhat- worked) and now my one-
request-per-object code works. I do reuse the status_vector across request objects, but everything
else is copied uniquely. (Yes, I know, it's a slight waste of memory.) I'm still not sure what I
did wrong the first time, but at least it works now.

Sorry!
