multiprocessing.shared_memory is a new module added in Python 3.8.0:
https://docs.python.org/3.8/library/multiprocessing.shared_memory.html
It was heavily influenced by the design of posix_ipc, but the proposed migration allows officially maintained, and more importantly cross-platform, support. This is particularly important on Windows, since posix_ipc is unix-only.

(Speaking of Windows, note that there is an MS-MPI, also supported by mpi4py. In principle it could work with our software, but I have no resource to verify this, nor is it supported on conda-forge.)
