When the process exits and runs destructor functions, there is no need to clean up these resources. Previously this could cause undefined behavior because higher-level subsystems had not been torn down first, e.g. threads still running when GThread was torn down. Skipping deinit in this case avoids teardown-time undefined behavior.
