Really, nothing, except that - with multiple streams - you have more 
events to potentially handle within your event loop.

Make sure that you're not doing anything - when handling one stream - 
that might be starving out events from other streams.  In particular, 
you should not be doing any 'busy waiting' (sittling in a loop, 
polling).  Remember that in an event-driven system, like this, all 
I/O should be asynchronous, handled only in response to events 
occurring within the event loop.

Correct.
