---------------------------------------

I'll have to review your development workflow but I've attached a patch that 
implements this.

> Currently the remote driver defaults to hard coded fetch size of 100 rows.  
> When a connection is operating in HTTP mode having such a small fetch size 
> can add enormous overhead.  This is especially true if TLS connections are 
> used and made worse if each connection flows throw multiple proxies.  
> Consider that 100K rows returned 100 rows at a time will make 1K HTTP POST 
> requests.  One might say that nobody should ever do that but some tools like 
> Spotfire may end up doing this.
