Is this enforced by the server not accepting another request from the  
client until it has a returned a result for the first one? It seems  
like there are times I might to do want to do something like spawn a  
task that's going to take a long time for the server to process and  
run it in a background thread, and then send other more immediate  
tasks in the client while the server chews on the long task I gave it?  
The server could then send an event to me to notify my background  
thread when it is done with the long running task?
