forEach loops forever for infinite streams

[Brian Goetz]

Yes, the previous behavior that threw ISE were just "training wheels" to 
get comfortable with the concepts.  If you perform a terminal operation 
that consumes all the input (forEach, into, reduce, etc), it will 
consume all of the future as well.

There are some terminal operations that are safe(r) on infinite streams, 
such as findFirst/findAny, and some intermediate operations that 
guarantee a finite result (such as limit).
