Ensure that attach ready channel does not block
We only use this channel in terminal attach, and it was not a
buffered channel originally, so it would block on trying to send
unless a receiver was ready. In the non-terminal case, there was
no receiver, so attach blocked forever. Buffer the channel for a
single bool so that it will never block, even if unused.
Fixes #8154
