Postgaardi

Postgaardi mariagerensis is a species of single-celled eukaryote in the Euglenozoa. Some have classified it in a class called Postgaardea along with Calkinsia, but as of 2009, Postgaardi is not well enough known to confidently determine its relationship with other organisms in the Euglenozoa.[1] Both it and Calkinsia do live in low oxygen environments and are covered with bacteria which live on their surface.[1]

gollark: Thus, help?
gollark: Alternatively, I can just make the adding-to-nickname-mapping bit happen at exactly the same time as the checking-if-nickname-exists bit but that would be really annoying.
gollark: Another would be very aggressive locking or something.
gollark: One possible way to fix this would be to have a central "broker" task which receives all state-updating commands ever and maintains stateful state, but this would be annoying too unless I can give everything else read access to it, and actually getting responses back would probably be irritating.
gollark: i.e. two people try and register with the same nick at exactly the same time, and then it has two people with the same nick because each time it checks it hasn't been written yet, and then everything breaks horribly.
