The documentation can simply say about TList:
Thread safe: no
Used non thread safe global variables: none
About TAVLTree:
Thread safe: no
Used non thread safe global variables: NodeMemManager, unless overriden by
SetNodeManager
No need for new terms. And everyone knows what to do to use the class in a
specific thread.
