Description
import logging.config costs ~29 ms and import logging.handlers ~26 ms, but most of what they
import is only needed conditionally based on feature usage (socket/HTTP/SMTP
handlers, the config socket listener, multiprocessing queue detection).
Apply lazy imports to the modules within the logging package while preserving finalization and shutdown expectations.

Research direction
Start with the logging.config and logging.handlers modules, measuring their current import costs and tracing imports used only by socket, HTTP, SMTP, configuration-listener, and multiprocessing-queue features. Confirm that lazy loading preserves finalization and shutdown behavior, then compare import timing and conditional feature behavior before and after the change.
