What Does This Do

ClassLoaderValue provides the same functionality as ClassValue, but for class-loaders rather than classes.

Note: the computed value should not have a strong-reference back to the associated class-loader, as that would stop the class-loader from being unloaded in the future.

Motivation

ClassLoaderValues don't require up-front sizing and are cleaned up in the background using a shared task. The period between cleanups was chosen to be 30s given class-loaders are rarely unloaded.

Looking good 👍

🔍 nitpick: ‏I would add a quick comment before the new task schedule to clarify the task goal and the chosen delay. This Agent part is already pretty packed with various stuff, that are not always easy to follow 😓 (and the comment is only in the PR, not in the commit message so harder to find). But that's nitpick 😇
