- fix problem with cmake, windows 'RelWithDebInfo' target, was giving error: "ImportError: No module named _socket" because of copying wrong files over.

- change interface code not to loop on a float value (clang warning), harmless, but with extreme cases an eternal loop would still be possible though unlikely.
