There's no optimization of the inc/dec, you use regular inc/dec
within a larger xbegin/xend block.
Actually you dont need to inc/dec if you do both in the
transaction. You only need to read the refcount. If somebody else
writes to the ref count the transaction fails.
So, you cannot succeed a transaction while somebody else decrease
the ref count.
Sounds right?
