• The build will now fall back to pure-python mode if the C extensionfails to build for any reason (previously it would fall back for someerrors but not others).

• If any callback of a PeriodicCallback or IOStream returns aFuture, any error raised in that future will now be logged(similar to the behavior of IOLoop.add_callback).
