Perhaps this is just me being dense, but.. if thrd is on the stack, I cannot
see what the problem is here.  In that case, the if statement will always be
true because each thread has its own stack.  If it's not on the stack, then
there's a potential programming error.  Is the goal to make it impossible to
make such an error?
