) SharedMemory.unlink() uses the unregister() function from resource_tracker. Previously it was imported in the method, but this can fail if the method is called during interpreter shutdown, for example when unlink is part of a __del__() method. Moving the import to the top of the file, means that the unregister() method is available during interpreter shutdown. The register call in SharedMemory.__init__() can also use this imported resource_tracker. (cherry picked from commit 9a458be) Co-authored-by: samtygier <samtygier@yahoo.co.uk>
