The proposal that you point to does not work unless the compiler 
supports thread safe local static initialization or you perform the 
locking yourself like I proposed earlier in this thread.

And is this portable ?  It sounds like a maintenance nightmare.

Also, the idea that you call every method that has a static local in 
main (before any threads are started) is very difficult when you use 
templates since it's impossible to know just how many of them exist.
