One-time initialization

At least one computer storage media storing computer-executable instructions that, when executed by a computer, cause the computer to perform a blocking method for initializing data in a multi-threaded environment, the blocking method comprising:

• allowing, in response to a first thread attempting to initialize the data and to an initialization state of the data not indicating “initializing” or “initialized”, continued execution of the first thread of a plurality of threads all being conventionally concurrently executed by at least one processor;
• and
• further allowing, in response to the allowing and to any of the plurality of threads not attempting to initialize the data, continued execution of the any of the plurality of threads.

The at least one computer storage media of claim 103, the blocking method further comprising blocking, in response to the initialization state of the data indicating “initializing”, any of the plurality of threads, other than the first-in-time thread, attempting to initialize the data while the initialization state of the data indicates that the data is “initializing”.

A system configured for initializing data in a multi-threaded environment, the system comprising:

• at least one processor configured for allowing, in response to a first thread attempting to initialize the data and to an initialization state of the data not indicating “initializing” or “initialized”, continued execution of the first thread of a plurality of threads all being conventionally concurrently executed by the at least one processor;
• and
• the at least one processor further configured for further allowing, in response to the allowing and to any of the plurality of threads not attempting to initialize the data, continued execution of the any of the plurality of threads.
