[omniORB] scanGranularity(0) bug under WinNT

[Ivanov, Roumen]

	Hi,
	omniORB 3.0.2
	WinNT 4.0 SP 5
	MSVC 6.0 SP 4

	I have the following combination of omniORB options:
		//--- Tune the ORB
------------------------------------------
		omniORB::idleConnectionScanPeriod(omniORB::idleIncoming, 0);
omniORB::callTimeOutPeriod(omniORB::serverSide, 0);
		omniORB::callTimeOutPeriod(omniORB::clientSide, 0);
		omniORB::MaxMessageSize(8*1024*1024);	// The default is
2MB
	#ifndef WIN32
		omniORB::scanGranularity(0);	// Bug under NT - looping
instead of waiting forever
	#endif

	The last one misbehaves under NT taking a lot of processor's time.

	Roumen
