I agree that the idea is nothing new, my observation/question/thought was
that the paradigm and larger architectural switch for openstack (and parts
of the larger python community) is new (even if the concept is not new)
and that means for those unaccustomed to it (or for those without
experience with node.js, go, twisted, tornoado or other...) that it will
appear to be similarily black-magic-like (complex things appear as magic
until they exist for long enough to be understood, at which point they are
no longer magically). Eventlet has that one benefit that it has been
around longer (although of course some people will still call it magical,
for the previously stated reasons), for better or worse.

Hope that makes more sense now.
