- * @todo Johan comment:
- *
- * ext->sendSignal should return something if send failed.
- * I.e., i think all methods sending a signal should return int
- * so that we can take care of errors. ALternatively take care of
- * the error like this:
- * if(ext->sendSignal(..) < 0 )
- * handleSignalError(...)
- *
- * or a combination....
- *
- * Should go through all places that sends signals and check that
- * they do correct error handling.
