I don't know how boost::function is implemented, but it should be 
possible that it can only throw if the function object contains state. 
And I think that should seldom happen.

If it doesn't contain state, it should be possible to fallback to a 
two-pointer representation, where function owns nothing (and thus 
doesn't need to allocate memory) and only references code and context. 
(that is to say, std::nested_function from the lambda proposal)
