Combine Lambdas and weak_ptrs to make concurrency easy
summary
Combining lambdas with shared_ptr and weak_ptr makes deferred thread dispatch simple by capturing a weak_ptr, checking weak_ptr.lock() before running, and dispatching the lambda to the simulation or network thread so no manual lifetime tracking is needed. Use make_shared for efficiency and consider scope guard for cleanup and exception safety. Example: schedule work 10ms–100ms later or add random 1ms delays to simulate latency that successfully turned a single player prototype into a multiplayer test.
