Hi,

Please review the following webrev that makes flatMap non-aggressive when pushing elements downstream if any downstream operation is short-circuiting.

This enables support for flat mapping to an infinite stream (assuming there is a downstream short-circuiting operation to terminate the stream computation).

Thanks, Paul.
