Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: As memory transactions have been proposed as a language-level replacement for locks, there is growing need for ll-defined semantics. In contrast to database transactions, transaction memory (TM) semantics are complicated by the fact that programs may access the same memory locations both inside and outside transactions.  Strongly atomic  semantics, where non-transactional accesses are treated as implicit single-operation transactions, remain difficult to provide without specialized hardware support and/or significant performance overhead. As an alternative, many in the community have informally proposed that a  single global lock semantics  [16, 9], where transaction semantics are mapped to those of regions protected by a single global lock, provide an intuitive and efficiently implementable model for programmers.   ,  explore the implementation and performance implications of single global lock semantics in a akly atomic STM from the perspective of Java, and  discuss why even recent STM implementations fall short of these semantics.  describe a new akly atomic Java STM implementation that provides single global lock semantics while permitting concurrent execution, but  show that this comes at a significant performance cost.  also propose and implement various alternative semantics that loosen single lock requirements while still providing strong guarantees.  compare our new implementations to previous ones, including a strongly atomic STM.
