/*
* 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.)
