History
The code name ''Midori'' was first discovered through the
PowerPoint presentation ''CHESS: A systematic testing tool for concurrent software''.
Another reference to Midori was found in a presentation shown during the ''Object-Oriented Programming, Systems, Languages & Applications'' (
OOPSLA) October 2012 conference, and a paper
from the conference's proceedings.
