OsiXprSolverInterface prints on stdout even if OsiDoReducePrint is and loglevel is set to zero in its messagehandler

Description

see http://list.coin-or.org/pipermail/osi/2010-May/000360.html and http://list.coin-or.org/pipermail/osi/2010-April/000340.html

Applying

osi->setHintParam(OsiDoReducePrint?); osi->messageHandler()->setLogLevel(0);

I am able to deactivate output for most solvers, except Xpress.
