I have a case where I use a map as a cache which are stored in the thread local storage using enumerable_thread_specifc. There's a method if called, has to flush out all the caches. Meaning a method call from one thread has to somehow modify all other threads' (of the application) thread local storages to flush everything out. Is this possible at all? At first glance it doesn't seem like it, but just wanted to make sure.Thank you very much.
