Actually, Access Control List is attached to the thread object. It's only
checked at OpenThread call (and other calls that use ThreadID). A handle

What is the difference between the return value (thread "handle") and
the lpThreadId parameter (thread "identifier")? I mean, if you have
LPDWORD id;
HANDLE h = CreateThread(..., id);
Is h simply a pointer to id (or a value identical to id)?
A thread is uniquely identified by its ID, but there may be multiple
handles referring to the same thread (see e.g. DuplicateHandle). The ID is
valid system-wide, the handle is valid within a single process only. The
handle, in addition to referring to a thread, also carries access control
list specifying what operations you are allowed to perform on it.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
