Optimize nif_process_ready_tasks for ~15% performance improvement#56
Conversation
- Replace asyncio.iscoroutine() with PyCoro_CheckExact C API (~2-3us/task) - Use stack buffers for module/func strings instead of enif_alloc (~0.5-1us/task) - Cache asyncio.events module alongside cached_asyncio (~1-2us/call) - Pool ErlNifEnv allocations with 64-entry pool using enif_clear_env (~1-2us/task) - Add mutex protection to env pool for thread safety Target: reduce from ~53us to ~45-47us per call in submit_task flow.
