I believe that one problem with this will be that the patched InnoDB code
that is used is from an older version, and porting the patch forward does
not add any value for xtrabackup, but would require significant resources.
Just an FYI, I have been working with Stewart on this and I feel this
is the way to go, even though it is not as clean as building against
mysql-source-5.5.
