And thank *you* for reporting and testing and staying with this.

I've committed the patch (as two separate patches: the first does the
pipe infrastructure, the second adds the code in autofs to enable the
use of it), and tried to comment on it extensively in the changelogs.

I also marked the patches for stable, but I would suggest that the
stable team wait a while before applying it, just to verify that we
don't have some crazy third autofs pipe user that does the packet as
many smaller reads. I don't think that's a sane thing to do, and I
don't think it happens, but by now I'm getting a big paranoid about
this whole thing.

Because I really hope this means that we can close this issue for good.
