Transient collections should guarantee thread visibility

Description

With changes from CLJ-1498, transients are still thread isolated but may move between threads during their lifetime which introduces new concurrency concerns, namely visibility of changes across threads.

Approach: Make all transient collection fields either final or volatile to ensure visibility across threads.
