This patchset supersedes below: [PATCH v2 0/7] migration: Better error handling in return path thread
Another note is that this might conflict with Fabiano's other patchset to fix postcopy race conditions, but maybe not. If collapse, I can rebase. Let me send this out still for early reviews. I dropped the last patch there (which wasn't clear on being beneficial) from last version, meanwhile added three more patches to address an issue reported from our QE team that one postcopy migration can stuck in RECOVER stage and never got kicked out. For more information of that problem, one can refer to the last patch commit message. Since this one covers more issues, I renamed the subject, and let me version it from v1. I still collected most of R-bs from Fabiano since last version (patches 1-6). Please have a look, thanks.
