      Description

      Goal: take a mysqldump of a running server with it's master's coordinates saved in the dump in order to be able to use the dump to rebuild a slave. Do this without stopping the slave.

      Problem: there is an option --dump-slave=2, but to my dismay this will stop the SQL slave thread the entire time. Why is this needed? And, furthermore - with such option, if you kill (gracefully. kill -15) the mysqldump process, the slave is left in the stopped state...

      Please, make it possible to take a dump of a running slave with master's coordinates, without having to stop it.

      Command used:

      mysqldump --single-transaction --routines --triggers --dump-slave=2 -A .....
