Sorry for the late response.
I used this patch for my extension in a way that you should always
detach after you are done using the shmem segment. So the situation
you described would happen in a brief moment, but once the extension
finishes its task, the shmem segment will be destroyed naturally as
all processes detach from it.
Would this not be applicable in other extensions?
