So why is this unique to the mqueue inode then? It might be helpful
to have explicit call stacks in the e-mail, in text form, when you
resend to LKML.

That's because the HTML file is ***huge*** (1.7Meg), and I'm having
trouble with my browser properly rendering it. In any case, the html
claims to be showing the counter examples and I'm still stuck on the
*example*?
