Thanks for the pointer. I have addressed all issues identified by ECC with
respect to the code that I have added with these patches.
Are you waiting for another version with these changes before reviewing
further? If so, I'll submit that now, otherwise I'll wait for your review
of the current version.
Thanks,
Tom
