I've actually done quite a bit of testing with cache bypass, but
admittedly not with the 1.6 branch or pre-release.

I think we need at least this for 1.6:
http://git.openafs.org/?p=openafs.git;a=commit;h=f2c6ae300a211460c24c87752cf9400b9e61ee1f

We probably want the other cache bypass related fixes/improvements
from master as well.
