A couple of beginner questions on basic_managed_heap_memory:

1) I want to access elements in the contiguous memory segment by using an int key,  rather than a char string. Can I declare something like this:

typedef basic_managed_heap_memory < 

   int, /* my key is an integer */ 

   rbtree_best_fit<null_mutex_family>,

   flat_map_index

   >  managed_heap_memory;

I need to lookup objects using an external integer ID but the ID can have any value (ie, does not match the 0-N array element order of my memory segment). 

2) If I want to insert multiple objects with the same char* name (ala multimap) can I create a flat_multimap_index?
