摘要：Aspects of the present invention are directed at providing safe and efficientways for a program to perform a one-time initialization of a data item in a multi-threadedenvironment. In accordance with one embodiment, a method is provided that allows aprogram to perform a synchronized initialization of a data item that may be accessed by

multiple threads. More specifically, the method includes receiving a request to initializethe data item from a current thread. In response to receiving the request, the methoddetermines whether the current thread is the first thread to attempt to initialize the dataitem. If the current thread is the first thread to attempt to initialize the data item, themethod enforces mutual exclusion and blocks other attempts to initialize the data itemmade by concurrent threads. Then, the current thread is allowed to execute programcode provided by the program to initialize the data item.
