Re: [boost] Thoughts on make_shared and shared_from_this in aconstructor

Another possible solution is to stick the "weak this" into a thread-local static member of enable_shared_from_this<Y>. This also works but (absent compiler support for thread locals) doesn't fit into the header-only nature of shared_ptr.

It could be added as a extra feature that only exists for compilers with support for thread local variables (or when threading is disabled). And since thread_local is in c++0x, it's no barrier for the feature being added at some point to std::enable_shared_from_this.
