Comment (by lou):

 Essentially unchanged as 0.97 moves to 0.98.

 You can use messageHandler()->setLogLevel() to adjust the log level of the
 OSI handler, and the !OsiDoReducePrintLevel hint to (try to) affect the
 print level of the solver. But this is admittedly clumsy. Most annoying,
 there's no way to get at the message handler for a CoinMpsIO
 object, which by default is annoyingly chatty.

 There's a lot to be said for virtual methods here, because Leo's right ---
 each underlying solver has its own i/o control.
