Okay, this error seems to be triggered by a NullPointerException which 
seems to arise when I try to fetch a non-existent document out of Redis. I 
am a bit of a noob, so perhaps someone can explain how this works. I'm not 
aware of using any of Clojure's concurrency tools in this (very simple) 
app, so how might the NullPointerException lead to 
RejectedExecutionException?
