3. Description
PyCharm's debugger replaces sys.stdin with a custom wrapper (pydevd / pydev_stdin) to capture console input. That wrapper calls debugger internals that rely on thread-local state. When a background thread (such as stdin-control thread) iterates sys.stdin, the debugger helper checks a thread-local attribute (e.g. is_lock_acquired) that only exists for the debugger's main thread. In other threads the attribute is missing, causing AttributeError: '_thread._local' object has no attribute 'is_lock_acquired'.
