ahhh... I thought this all sounded familiar. It surfaced a couple of
years ago, and this was my summary of the intent at the time:

http://lkml.indiana.edu/hypermail/linux/kernel/0609.1/2106.html

It all went round and round for a while, but I don't think anything got
merged. In fact I can't even find Ben's original little spufs/cell
NOPAGE_RETRY code in the tree, an I thought we merged that. Confused.

The questions are, of course: does this new code address the issues
which were raised at that time?
