The built-in objects in LV do tend to be reentrant. They are always
threadsafe, even when the access must be serialized such as for UI
actions. When the API has a connection ID or other reference to work
off of, they connect directly to lower OS APIs and are as reentrant to
the extent the lower level APIs allow.
