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
Personally, I'm fairly new to the whole multi-proc scene so I'd really
appreciate some enlightenment!
