[Mono-osx] Debug embedded OSX app

[Duane Wandless]

Here is my create process code.  Is this the code in question?

                        Process browser;
var psi = new ProcessStartInfo ("open",
"/Users/me/Src/sandbox/nov05/svn/working/PFiles/build/Debug/PFiles.app") {
UseShellExecute = false,
RedirectStandardOutput = false,
RedirectStandardError = true,
};
psi.EnvironmentVariables.Add ("MOON_SOFT_DEBUG",
string.Format ("transport=dt_socket,address={0}:{1}", dsi.Address,
dsi.DebugPort));
 browser = Process.Start (psi);
ConnectOutput (browser.StandardOutput, false);
ConnectOutput (browser.StandardError, true);

I did modify the Waiting for debugger to connect message to print out both
DebugPort and OutputPort.  OutputPort is zero.

protected override string GetListenMessage (RemoteDebuggerStartInfo dsi)
{
return string.Format("Waiting for debugger to connect at {0}:dbg{1}:con{2}",
dsi.Address, dsi.DebugPort, dsi.OutputPort);
}

Thanks,
Duane
