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

I would say this as a bug instead of an enhancement.

This is one of the critical issues with large files for clients behind 
router/firewall. 

Please prioritize this fix.

> For routers/firewalls that terminate idle connections, a separate heartbeat 
> mechanism may need to be implemented to keep the control connection active.
> Some potential issues:
> * Synchronization between a heartbeat write and a __getReply() on an active 
> control connection command;
> * Should use the NOOP command as a heartbeat signal;
> * Make the timeout configurable;
> * Default SocketImpl::setKeepAlive() wont do here.
