HI. I don't have a full answer, but a few pointers:
- Your xquery2 is the same as xquery1 (includes sleep). This is probably not what you meant to include as it does not match your description where you say that there si no sleep on xquery2 - In the same statement you update the node and also read it back via doc() to verify it. This does not work this way in the query console. So you may be seeing some confusing results due to this. - I do not believe that the sleep will lock the document for 10 seconds in your example, so I don't think you should expect to see anythong blocking for that reason. Perhaps spawning your two samples would help you on your way. If nothing else, it will take the query console out of the equation.
