Most of the time, the information is available and filesystem_error works 
well in practice. Knowing the function name, arguments, and error code (or 
error message) is usually sufficient to solve the problem, without further 
debugging.

Earlier versions did not have as much information, and there were repeated 
complaints from users. Once the current scheme was adopted, the complaints 
stopped.
