 This hack, if working, would be useful when both loading XAML and
 under "normal" (code) circumstances.

+while tracking another issue I found out that a single TextBlock in an
+XAML file can call TextBlock::CalcActualWidthHeight 6 times (of course
+that depends on the number of attributes) all of them required to
+create/destroy a cairo context.
+
+TextBlock::CalcActualWidthHeight w 0 h 19 destroy TRUE
+TextBlock::CalcActualWidthHeight w 21 h 18 destroy TRUE
+TextBlock::CalcActualWidthHeight w 10 h 9 destroy TRUE
+TextBlock::CalcActualWidthHeight w 9 h 9 destroy TRUE
+TextBlock::CalcActualWidthHeight w 10 h 9 destroy TRUE
+TextBlock::CalcActualWidthHeight w 10 h 9 destroy TRUE
