This seems like the wrong mailing list for an in-depth discussion of it.

Nothing has changed that I am aware of. I’m not sure what GCC bug you are referring to.

Lack of control of what thread the destructors run on was one major issue that caused us to do this. The threading issue created serious problems on the iPhone platform as atomic strings were destroyed on the wrong thread.

The ability to get extra speed on shutdown by opting in to this mechanism is also a benefit.

For all the ports that Apple uses, shutting down the library without shutting down the entire process is a non-goal.
