Hi,
This patch implements optimizations for the limit/substream operations when
input to those operations have certain properties (corresponding to known size
or unordered) which helps to avoid out of memory issues (not all, we still have
some more work to do).
The {Xxx}/Stream.generate methods have been modified to generate a known
infinite stream of unordered elements. Previously an ordered known infinite
stream of elements was generated, making it particularly prone to OOMEs.
