_.CopyPaste_ work natively and under Dr. Memory, but fail under plain DR on my win7 laptop:

[==========] 2828 tests from 463 test cases ran. (485992 ms total)
[ PASSED ] 2823 tests.
[ FAILED ] 5 tests, listed below:
[ FAILED ] BookmarkUtilsTest.CopyPaste
[ FAILED ] BookmarkContextMenuControllerTest.CutCopyPasteNode
[ FAILED ] BookmarkContextMenuTest.CutCopyPasteNode

ConnectionTesterTest.DeleteWhileInProgress also fails under drmem when run
as just one test ( issue #331 ), and
ExtensionUITest.GenerateExtensionsJSONData fails natively on this machine.
