And anyway, I feel a big problem for applications committing RC RO txns
so much often that it could possibly affect the performance. This sounds
like a feature misuse.

I agree that a long running RC/RO transaction produces exactly the same

results as a series of short RC/RO transactions, and that the former is more

efficient than the later.  On the other hand, if you have to run very short 

transactions, aren't the RC/RO variety cheaper than the alternatives?
