I am afraid the usage of thread_specific_ptr as a local static object is
The constructors might be called when "first time control passes through
This would be bad. As far as I know thread_specific_ptr is expected to
be constructed before
Also what does "first time" mean when MT is involved? The standard does
not know about MT.
Will it be called twice?
I think the poiner should be moved to file scope.
