Reply stream in Bosh

Hi,
I am currently implementing a J2ME Bosh client and I did not
see this  
specified. Assume non pipelined mode.
Assume I have a pending request and my local client wants to
send a  
message. It opens a new request and sends the message. What
happens to  
the reply?
Should the reply come back on the pending request or the new
request?
I think that it would make sense if the newly created
request does not  
become a response. This way it could be a fire and forget
thing.  
Otherwise the client will be waiting on the old stream for a
response  
when there will be none.
