   @villebro thanks for the investigation!
   
   > So apparently this is mostly MySQL specific (I'm assuming you are using MySQL?), i.e. the recommended course of action is to try the update, catch the deadlock exception and try again. As I hope this isn't common for other backends, perhaps this should be wrapped in a method in the MySQL spec. Not ideal, and might end up cluttering the codebase, so perhaps we need to think this through before making any changes..
   
   I think it's not only MySQL-specific, but configuration specific. It happened in our production MySQL database, but when I tested on my laptop using a local MySQL I couldn't repro it.
   
   I'm going to try reproing against our staging DB from my laptop.
