Hi, I am trying to store a uniqe email using transactions, but I would always get more database entries than expected. I wrote a minimal example: http://sprunge.tillmanns.me/2de2bdda90 if I make the code non concurrent I get the expected result. Do you have any idea what I am doing wrong?

Why am I not able to keep a value unique using Transactions?
