+  
+  It also allows to compute/convert each kernel pointer registered in the
+  table to a user handler, that can be checked.
+
+  The "user" handler is composed by the index in this table
+  (the low INDEX_SHIFT bits) and the low bits of the "local" pointer
+  shifted by INDEX_SHIFT are stored in the high bits:
+
+  handle bits: 31 ................................ 12 11 ...... 0
+              | lower bits of of the local pointer   |   index   |
+
+  This allows a straight translation from a user handle to a local pointer
+  + a strong check to validate the value of a user handle.
+  The reverse translation from pointer to a user handle is
+  slower as it requires an explicit search in the list.
