Correct and a couple of other interesting variables:

_Thread_Heir points to the highest priority ready thread
which may or may not be the same as the executing one.

_Thread_Allocated_FP points to the thread whose FP
context is currently in the FPU.  Again, this might not
be the same as _Thread_Executing.
