[issue37652] Multiprocessing shared_memory ValueError on race with ShareableList

[Davin Potts]

Davin Potts <python at discontinuity.net> added the comment:

Apologies, one of the quotes in my previous response should have been attributed to @mental.

I think @pierreglaser phrased it very nicely:
> shared_memory is a low level python module. Precautions should be made when handling concurrently the shared_memory objects using synchronization primitives for example. I'm not sure this should be done internally in the SharedMemory class -- especially, we don't want to slow down concurrent READ access.


Per the further suggestion:
> +1 For a documentation addition.

I can take a crack at adding something more along the lines of this discussion, but I would very much welcome suggestions (@bjs, @mental, @pierreglaser)...
