Message348299
When running the attached on 3.8 and 3.9 (master) I get the following:
Process Process-3:
Traceback (most recent call last):

Either this is a documentation error, and the docs for shared_memory should state that the ShareableList does not have atomic operations and so this is unsafe, or this is a suspicious behaviour. I'm not sure which.
I could also just be using the library totally incorrectly. |
