Description

Found this when digging HBASE-28522.

First, this is not safe as MTP does not like DTP where we hold the exclusive lock all the time.
Second, even if we hold the exclusive lock all the time, as showed in HBASE-28522, we may still hang there forever because SCP will not interrupt the TRSP.
