Re: future.error == nil

Well, describe your setup a bit more please: Do you use multi-threading in this 
codebase? If so, how do you share memory / make the threads communicate? What 
other libraries do you use? Can you share the code? Can you run it with 
`-d:useSysAssert -d:useGcAssert`? What are the errors then?
