An ASGI channel layer that uses POSIX shared memory IPC as its backing store
(only works between processes on the same machine).
Beta - please file issues if it doesn’t work or fails weirdly (shared memory
and IPC can be tricky)
Usage
You’ll need to instantiate the channel layer with a path prefix to create
IPC objects underneath; any channel layers with the same prefix will talk to
each other.
prefix: Prefix to use for IPC objects in the root namespace. Defaults to asgi.
