We do this in OpenSim.exe to hide output when unmanaged dll are scanned by mono addins. Libomv has hard-coded path to "." for the openjpeg libraries, causing output to the console when they are scanned. We will cover this up for now, then look at getting libomv to look for the libs outside the "." later.
