Has any work been started on that? If not, maybe it would be time as part
of this rush to implement the protocol in winbind from scratch? At least
the non-mmap piece looks not too complicated. If sssd has no resources
to spend, maybe someone could re-implement this in Samba proper.

What protocol do you have in mind? Samba already implements
an abundance of RPC-style protocols that are capable of
async requests, maybe we can ride on one of those? The sssd
protocol header seems to have some reserved fields. Use one
of those as a request id field?
