Subject: ver_linux: proposed implementation feedback request

Thanks very much for everyone's feedback.

Instead of flooding this mailing list with another bunch of ver_linux
patches, I thought I would post another implementation, and see if you
find any of the proposed changes worth submitting as a patch. I will
be happy with whatever feedback you can give me. And we will leave it
at that. Thanks.
