You probably shouldn't be concerned.  I can't say what that thread is, but
if your speculation below is correct, I can say why it's there.

All threads, Windows or Cygwin, go through a hook (threadfunc_fe) that
gives them a thread local storage object at the base (approximately) of
their stack.  When they die, the destructor for that object is called.

(I hope I got that close to right.)
