Peter, I looked at GError and it seems to require
adding a GError ** argument to every function that can
fail, which is pretty ugly. Overall, I find GError 
clumsy.

What I would prefer is the simple errno-like behaviour:

1. call a function
2. check the return value 
3. if it's NULL or < 0 or whatever convention we agree on, 
   print the error string

The main problem with this is how to make error codes
and strings thread safe. Thoughts?
