Interesting! To my excuse that was added recently while I was on vacation :-)
I've just looked at the code and it is broken:
- the readonly flag is set on prepare with the value returned by last enlisted XAResouce
(bad!!)
- so on commit, if last enlisted XAResource returned r/o status, no commit is called on
*any* other enlisted resource (bad! bad! bad!)
