When you turn off the tap, the water stops flowing.

There's no point in trying to use the connection. The client won't know
that it's disconnected unless it tries to talk to the server.
So do a low-impact query. Then, you should get an exception, which you
handle *first*, then use ForceDisconnect to reset the client. This will
invalidate the now unreferenced connection handle and you'll be ready to
connect again.

I use a call to IB_Connection.Gen_ID(MickeyMouse,0), but anything
"harmless" to the state of your app will do to raise the exception.
