DS_BINARY_SEARCH_TREE status ?

Hi,
I was wondering what the status of the DS_BINARY_SEARCH_TREE_* classes 
is. I was trying to use the DS_RED_BLACK_TREE_SET and found it to be 
quite buggy. I already spent several hours trying to fix the subtract 
feature. But fixing one bug always seems to uncover another one, which 
is quite frustrating.

Thanks,
Jann
