Overview
A resource management pattern that ensures proper shutdown of background I/O threads and release of hardware resources after inference completion.
Description
FlexLLMGen uses background copy threads for async disk I/O. These threads must be explicitly terminated after inference to prevent resource leaks. The close_copy_threads pattern propagates shutdown from ExecutionEnv through to TorchDisk's background thread pool.
Usage
Always call env.close_copy_threads() after the final generation call to cleanly shut down disk I/O threads. This is required for graceful program termination.
Theoretical Basis
Background thread management follows a lifecycle pattern: threads are created lazily on first disk I/O, run continuously during inference, and must be explicitly joined on shutdown. Failure to close threads may cause the process to hang on exit.
