nit: I'd personally group all critical failures at the end of each Create*()
method (or anything that can return NULL and bail), as there's no reason to do
more work if a critical failure will waste all of it later.

[Dan Beam, 2012/12/06 22:00:14]

whooops! I meant group all critical failures at the *beginning*.
