> When we had a fast connection doing SSL to an origin server, and a slower 
> connection to the client, and not very much CPU, the SSL VConn code would 
> start to spin reading data from the origin server, and not breaking out of 
> the loop at all to send data to the client.  As a result the throughput to 
> the client would drop to zero and ATS would get a bit bigger.  So my proposed 
> patch is to have the SSL VConn code not stay in its loop when it has some 
> data that it has read, this matches how non-SSL network VConn's work.  My one 
> concern with this is that there might have been a good reason for that 
> looping, and that this might slow down cases when things are working properly.
