Revert rev 2.35. It was based on erroneous reasoning -- the current thread's id can't get duplicated, because (of course!) the current thread is still running. The code should work either way, but reverting the gratuitous change should make backporting easier, and gets the bad reasoning out of 2.35's new comments.
