Safety change to ensure read/black trees (used with heap tables) works on 64 bit setups where ulong <> size_t
Don't retry test cases by default
Fixed bug where we could (under unlikely error conditions) access not initialized variable

  Don't retry test cases by default
  This makes it too easy to miss failures and we have anyway to fix race conditions, not ignore them.
