Well, I'd love to try something, but I'm now more in need of using the 
BzrPoller in 0.8.7 branch, so I'd like to address that first.
Also, other interested people on the list seem to be more advanced on 
this than I am, and proper testing (including real-world) for all these 
conditions would take some time.

Pierre: any chance to see your code, even if not ready for proper 
integration ?
