Updated 4xx next branch

[Josh Boyer]

Hi All,

The following patches have been pushed to the next branch of the 4xx tree.
As usual, I'll let them sit there for a bit before asking Paul to pull.  If
I've missed any patches, please let me know.  We have lots of time before the
.28 merge window opens, so don't worry too much.
