I guess the "Terminate" field is actually about cache coherency.
Yes, but as mentioned earlier it's in general completely useless to
force the overhead of cache coherency for it. By design it's not
something that will be checked immediately after it gets set, so who
cares if the target thread doesn't see its new value immediately?
If you do care, then you need some other way to signal the target thread
to immediately drop what it's doing, but then there is no point in
checking the Terminated property anymore since that signal will already
have performed the same function.
The new, virtual TerminatedSet method can be used for such a signal.
It's called after FTerminated was set to True an can be used for example
to trigger an event the thread might be waiting on.
