Python has integrated shared memory into standard library starting from 3.8 (https://docs.python.org/3/library/multiprocessing.shared_memory.html), which provides a user friendly API to access shared memory across unrelated processes using names. But, there are no synchronisation mechanisms present in the standard library to prevent race conditions when shared memory is accessed across unrelated processes.

I had earlier created an enhancement issue at bugs.python.org, which contains more detailed discussion on the same. I am posting this here after a suggestion from a Python contributor.

Feedback on the same will be very helpful.

What you are asking for it the ability to open a named semaphores with the limitation of the current implementation that the semaphores must can only be shared with child processes?

Please confirm that I have understood.

If that is it sounds like a reasonable request to me.
