Hmm, patches 5-11 seemed to be dropped, and I sent out 12 patches of
the latest sframe work that I can't find anywhere. I think my ISP is
thinking I'm spamming so it dropped the emails. That's all I can figure.

I originally used kernel.org as my smtp server, but gmail starting
putting my emails into spam because kernel.org can't validate
goodmis.org with DKIM (my DNS has kernel.org set for SPF, but that's
not enough these days :-p).

So I went back to my ISP (hover.com) as my SMTP server, but now I think
it doesn't like my scripts that sends out a series of patches to a lot
of people. It likely thinks I'm a spam bot (although maybe I am!).

I guess I'll change my scripts to use rostedt@...nel.org to send and go
back to using kernel.org as the SMTP server for my scripts. :-/

Expect a resend. Sorry for all the noise.
