Whoops, spelled openafs-devel@openafs.org incorrectly.

I finally got around to doing the bisection on this, which points to 
0284e65f97861e888d95576f22a93cd681813c39 as the first bad commit.

     dir: Explicitly state buffer locations for data

I don't see anything in that commit that would make the bug obviously specific 
to FBSD/UKERNEL ... is anyone else seeing this 'all buffers locked' issue on 
master?
My test case is running 'svn up' on the FreeBSD source tree (a ~1.6G checkout).
