+Logic behind bulk insert optimisation is simple.
 
+Instead of writing each key value to b-tree (that is to keycache, but
+bulk insert code doesn't know about keycache) keys are stored in
+balanced binary (red-black) tree, in memory. When this tree reaches its
+memory limit it's writes all keys to disk (to keycache, that is).  But
+as key stream coming from the binary tree is already sorted inserting
+goes much faster, all the necessary pages are already in cache, disk
+access is minimized, etc.
