[New-bugs-announce] [issue16284] concurrent.futures ThreadPoolExecutor keeps unnecessary references to worker functions.

[Mark Dickinson]

New submission from Mark Dickinson:

The ThreadPoolExecutor unnecessarily keeps references to _WorkItem objects.  With the attached patch (which lacks a test), all tests still pass, and the references are removed as soon as they're no longer needed.
