fwrite can fail

[Danack]

The fwrite here can fail, generating a notice but continues to run in a presumably bogus state.

So I guess the code so check the return value.....and possibly suppress the warning? (shakes fist at PHP's 'error' model)

Exception:

Notice: fwrite(): send of 32 bytes failed with errno=65 No route to host in /documents/projects/github/FlickrArtaxService/vendor/daverandom/addr/lib/Addr/Client.php on line 182

To fix: Ensure that writes are checked for success, and fail if not Open question: should a failure roll down to the next lookup in the stack or return failure immediately?

Fixed in 0.2 and master
