Yup, the first priority is to get the 2.6.33 code fixed up.  It is
unwise to assume that we'll be merging some other patch some time in
the future.

Macros are unpopular, for good reasons.  But the case for a
template-based container such as this is a good one.  However I worry
about the code bloat whcih the macro version might add.  We worry about
all this later on.

I shall.  Stefani, pelase review those patches for 2.6.33 suitability. 
Let's not worry about a big rewrite at this time.
