Trigger a timeout of FTWRL when performing SST
Hi, It would be convenient in the case where SST is triggered that a timeout value is applied when trying to obtain the FTWRL. A use case is when SST chooses a node with a long running transaction, it will never get lock, and potentially impact subsequent queries to this server. This can lead to an outage scenario where all connections and resources are consumed and then denial of service to the application occurs.
See feature request to XtraBackup that would apply to 5.5 (since I don't think we plan backporting the Backup Locks to 5.5?) that indicates addition of timeout to XtraBackup FTWRL and ability to roll this back.
