Elevated and Severe Hub Loads with v2.3.4

Huh, okay so the word is that this is "fixed".

Fixed high CPU usage/memory leak under certain conditions.

@gopher.ny Is there any chance we could get some detail on what these certain conditions were? It would rather restore my confidence. At the moment this platform-disrupting bug is just subject to mystery and intruige, two things I don't like powering my home. :wink:
