+/*
+  Asks the master for the list of its other connected slaves.
+  This is for failsafe replication : 
+  in order for failsafe replication to work, the servers involved in replication
+  must know of each other. We accomplish this by having each slave report to the
+  master how to reach it, and on connection, each slave receives information
+  about where the other slaves are.
+
+  SYNOPSIS
+    update_slave_list()
+    mysql           pre-existing connection to the master
+    mi              master info
+
+  NOTES
+    mi is used only to give detailed error messages which include the
+    hostname/port of the master, the username used by the slave to connect to
+    the master.
+    If the user used by the slave to connect to the master does not have the
+    REPLICATION SLAVE privilege, it will pop in this function because SHOW SLAVE
+    HOSTS will fail on the master.
+
+  RETURN VALUES
+    1           error
+    0           success
