Actually, that feature exists right now. Look for calls to
we_are_hibernating() in various places in the code (command.c and
connection_edge.c in particular).

As soon as the first stream is refused with reason
END_STREAM_REASON_HIBERNATING, the client will give up on that circuit
for new streams, and try a new circuit -- see edge_reason_is_retriable().
Hope that helps,
