Hi,
Plone 3 to 4 migration occasionally triggers a POSKeyError during
transaction commit. See http://rpatterson.net/blog/poskeyerror-during-commit
I encountered the issue yesterday.
I committed a test and a fix in branch 3.10.
https://github.com/zopefoundation/ZODB/commit/6457bcfd07b3b77f240cbc6d60f222f0d40e8d5d
Before the fix, the test triggered a traceback very similar to the one
seen when migrating Plone.
As I am not an expert of ZODB internals, I'd like someone to review my
fix even if the test suite does not break.
Thanks
