"Agreed"? That last restriction is a deal-breaker.
OK, I should have said *if wal_buffers are full* XLogInsert() cannot
advance to a new page while we are waiting to send or write. So I don't
think its a deal breaker.
Oh, OK, that's obvious --- there's no place to put more data.
Each WAL sender can keep at most one page locked at a time, right? So,
that should never happen if wal_buffers > 1 + n_wal_senders.
