If we want to do this, perhaps we can make this configurable via a new
bit in the shmflag argument to shmget(2)?

Something like IPC_CLOSEONEXIT?

I _don't_ think that we should change the default behavior for these

removed) is well-known, and depended on in enough cases to make this an
unexpected change.
