  You can learn a lot about a community, a product, and a company based on how they respond to bug reports. Promptness, formality, details and politeness are all incredible indicators about what's going on under the hood.

    And what did you make of their reply?

  By the way, the risk of a collision with 10 times more members is much more than 10 times as likely, due to the birthday paradox.

    Yeah, I realised I got the probability wrong but haven't written a follow up (typing on my phone is tough, writing code is impossible). The probability of being able to update an old version of the document, is simply 1/ 65536. That's a very high probability given thousands of documents or a modest number of competing updates. The biggest issue is that it's undetectable and non-deterministic: the update that should fail will succeed silently and it can happen at any time. I'll re-open the bug in the morning with a proof-of-concept.
