	Thread-safety & locking

	Alle durch die Schnittstelle nach aussen angebotenen Funktionen, werden
	gegen Reentrance grob-granular mittels eines kritischen Bereiches gesperrt.
	Damit sind auch parallele Calls auf unterschiedliche Methoden der Klasse
	unterbunden. Sollte dies zu Performance-Problemen fhren, kann ein
	verfeinerter Locking-Mechanismus entwickelt werden. Zunchst mal aber so.

	Sichere Ausnahmebehandlung

	Problem: Intern knnen auch andere Typen von Ausnahmen als
	CVAException geworfen werden. Nach aussen hin drfen
	aber NUR CVAExceptions geworfen werden (Konsistent)

	Lsung: TRY-/CATCH-Makros fr abgesicherte Bereiche in allen Methoden
	der externen Schnittstelle. Zweistufiger Aufbau.
	1. (innen) Fange alle Exception-Typen und konvertiere sie in CVAExceptions
	2. (aussen) Fange die einzig mgl. CVAExceptions und biete
	gemeinsamen Catch-Weg zur Problemlsung (Aufrumen) an

	try {
	try {
	// Code ...
	} catch (ITAException& e) {
	// Konvertiere zu CVAException
	} catch (VistaExceptionBase& e) {
	// Konvertiere zu CVAException
	} catch (...)
	// Generiere unerwartete CVAException
	}
	} catch (CVAException& e) {
	// Gemeinsames Aufrumen
	}

	Beispiel:

	VA_TRY {
	// Code ..
	} VA_CATCH {
	// Mach was ...
	}

	Hinweis: Initiale/finale Geschweifte Klammer fehlen, da diese hinter die Makros geschrieben werden
