The load_single_library method is a convenience method for a common case. In
general, I recommend using a shared_library object instead. I believe this
case is detailed in the latest documentation.
However, you are probably right that I need to change the
load_single_library function to either return a bool or throw an exception.
Thanks for the heads up, and sorry about the time lost debugging.
