libmongo will try each node in your CSV of nodes, there is no going
around this. Now, while your usage of two completely different clusters
in the same connection string seems to be *non-conventional* (I don't
recall any documentation advising this, all Mongo docs talk about
connecting to either a *replica set*, or to a *list of* *mongos*
servers), I still think it could work. Maybe just configure the
"connectionTimeousMS" parameters (or others??) and see if you can get
libmongoc to time out faster on your 1st cluster, when it goes down.
