However, I asked and apparently we've been seeing that code throw an exception on a regular basis. This is in the context of a larger c++ application... I've been trying to think of what reason could cause the lazy initialization code to throw an exception... The only case where it *should* throw is if there's recursion on initialization, but there is none in our code.
