Fixes #419 - memory leak.

 ## [Unreleased]
 
+
+### Fixed
+
+- Eliminated small memory leak for @disable tests.   Accomplished by switching to gFTL v2 implementation of Map.
+
+### Changed
+
+- Made annotation map a component of Test rather than using inheritance from StringTestAnnotationMap.  Arguably looser coupling, and was explored as part of chasing small memory leak mentioned above.
