Adding an error message is a good idea.

The spec does call for some additional info available in the progress events
thru these attribute values. These aren't implemented yet in webcore (or
chrome).
- lengthComputable, should be true
- total, the number of URLs to process
- loaded, the number of URLs that have been processed (downloaded or skipped)
