ABSTRACT:
A system and method are disclosed for providing a synchronization mechanism for access to shared information. According to an embodiment of the present invention, a lock with more than one part can be obtained or leased by writing to the first part, writing to the second part, reading the first part to determine whether the first part reads what was written to it, and obtaining the lock if what is read is the same as what was written.
