 * TODO #27 : Hash-Map with Worst Case property                  :ENHANCEMENT:
 
 Specialize hashmap with O(ln(n)) worst case:

+Open Point: how to do GC of such object in an efficient way
 
-* based on chaining that points on
+Not a good idead: worst case will still be O(n) due to the hashmap
-* a red/black tree with the 
+reallocation. Best to use a B+TREE directly in this case.

 * TODO #26 : Hash-Map for huge objects                          :ENHANCEMENT:
 
 Specialize Hashmap for huge objects on supported hardware:
 
-* based on OA hash map of taggued pointer (needs space for tagging)
+
-* low bits = low bits of hash
+based on OA hash map of taggued pointer (needs space for tagging)
-* pointer to object { key, hash, value }
+low bits = low bits of hash
+pointer to object { key, hash, value }
 
 Can detect collision without dereferencing object with 1/2^lowbits chances.
 Reduce cache usage ==> Shall be faster.
