Thanks.  I think David and I have both been improving the error handling
in places that we touch, but we need a more systematic approach to it.
I have been thinking about starting an automated test suite for 0.4.0,
as such might have prevented a few of the minor issues that we've seen.
Any contributions that you feel like making... send the patches. :)
