Comment(by rgommers):

 You're right about the performance scaling. Adding the Press and Rybicki
 algo would be nice as an option I think if you have time for it. But if
 not, this can go in pretty much as-is IMHO.

 About the test failure, a lot changed with floating point errors and NaN
 handling since numpy 1.3.0. For me it works fine with 1.5.1.

 I've regenerated the C file from Cython sources (this is not done during
 scipy build) and changed the line breaks in the tutorial:
 https://github.com/rgommers/scipy/tree/lomb-scargle

 It's up to you whether you want to implement Press/Rybicki first, or
 continue the discussion on-list about the naming and inclusion in
 scipy.signal.
