- * No magic constructor behaviour, as is de rigeur for XPCOM.
- * If you must perform some initialization, and it could possibly fail (even
- * due to an out-of-memory condition), you should use an Init method, which
- * can convey failure appropriately (thrown exception in JS,
- * NS_FAILED(nsresult) return in C++).
- *
- * In JS, you can actually cheat, because a thrown exception will cause the
- * CreateInstance call to fail in turn, but not all languages are so lucky.
- * (Though ANSI C++ provides exceptions, they are verboten in Mozilla code
- * for portability reasons -- and even when you're building completely
- * platform-specific code, you can't throw across an XPCOM method boundary.)
