+PYSIDE-1735: Testing different relax options for Enums
+
+This test uses different configurations and initializes QtCore with it.
+Because re-initialization is not possible, the test uses a subprocess
+for it. This makes the test pretty slow.
+
+Maybe we should implement a way to re-initialize QtCore enums without
+using subprocess, just to speed this up??
