Description Jeremy Orlow 2009-11-04 19:03:44 PST 
Calling SecurityOrigin::databaseIdentifier on LocalStorage's background thread is not safe.  databaseIdentifier does a bunch of string concatenation which ref-counts StringImpls in some cases.  This was caught by valgrind thread sanitizer: http://code.google.com/p/chromium/issues/detail?id=25645

There's no way to test for such racyness, unfortunately.
