looks like threadid is assigned to getcurrentthreadid in an

Correct. GetCurrentThreadID always calls through the thread manager to
retrieve the current thread's ID while ThreadID is initialized in the
thread's initialization. This make a difference if you're dealing with
external threads (those not started through the RTL, but from e.g. C
code). Though depending on the threading implementation it /might/ be
that it sets up ThreadID nevertheless. In essence: Best use
GetCurrentThreadID.
