I've tried to stick to the Intel patches as closely as possible,
and - yes - I think some of the infrastructure can and should be
factored out.  At the moment it's difficult for me to decide
_which_ parts can be extracted as I don't know how transactional
memory works on other platforms, e.g. Power.

Ups, that looks like I merged some changes that into the wrong
patch.  I'll post updated version of the patches in a minute.
