It looks like this variable is not used anywhere. Am I wrong?

I didn't change anything regarding _boot_pid variable but it's used in can_send method to perform fork detection.

I may not be following correctly, but why are you releasing the lock in a function that mainly prints a diagnostic of the agent?

Normally, we were using the locked() method to check if the background_report_check is locked or not but as we moved to RLock, this new object doesn't have this method. We acquire the thread without blocking and release it immediately.
