Hi Andrey,

Is there interest in having a boost singleton? A preliminary implementation of it could use boost::once. Then all lazy initializations would happen through that interface.
Just a thought.
I think a generic implementation of a thread-safe singleton is a nice idea. I encounter this problem quite often. Although, once-based implementation doesn't suit me very well in this case.
What kind of solutions have you come up with for lazily initializing singletons in a thread-safe manner? What are your reasons for not preferring a boost::once implementation? I can only think of boost::once based or platform specific, which scares me, to be frank! The solution to the problem seems to be a function of hardware and OS primitives which (I thought) pthread_once/family solve as nicely as you'd want. Personally, I'm fairly new to the whole multi-proc scene so I'd really appreciate some enlightenment! Sohail
