Occasionally, yes. The issue occurs when two messages arrive at about the same time for the same new disposable address. They get processed at about the same time, and because neither one sees the other, they both create a record. We've left this unfixed because a) it's rare, b) it's harmless, in that it has no effect on the functioning of the service, and c) the only fix we can think of would impact the performance of the system greatly.
If you send me an email or a PM, I can delete the duplicates.
