+    SignedLongIntegerArrays store 64bit signed integers in the range 
+    -16r8000000000000000..16r7FFFFFFFFFFFFFFF.
+    In contrast to normal arrays (which store pointers to their elements),
+    signedLongIntegerArrays store the values in a dense & compact way. 
+    Since the representation fits the underlying C-language systems representation
+    of signed longlong's, this is also useful to pass bulk data to c primitive code.
+    (the system makes certain, that the first longlong is aligned as required)
