I'm not excusing this particular case, I'm just explaining the perspective of most developers regarding synchronous versus asynchronous operations. In this particular case there's no reason to do it synchronously, since multiple processes are involved anyway. The crash handler should definitely not be waiting on a network operation to let the process terminate (that's not even getting into whether crash dumps should be getting uploaded by default to begin with), and the fact that this is a central part of the operating system's UI is even more egregious.
