Comment (by andysem):

 Which implementation are you referring to?

 > First of all, once_block_flag is not thread safe.

 What makes you think so? It is POD, and all its modifications in the
 library are made in a thread-safe way (given that you use the multi-
 threaded build of the library).

 I'm well aware of that, and that's the reason why once_block_flag is POD.
