摘要：
A software transactional memory system is provided that provides privatization safety. The system identifies situations where the completion of a transaction may be expedited because a privatization artifact will not occur. The system determines whether a privatization artifact may occur using a read and write set intersection test, transactional variables, pessimistic locks, or declared privatizing transactions. If a privatization artifact will not occur for a transaction, then the system may allow the transaction to complete prior to one or more earlier transactions.
