+- The memory manager now uses a variant of the TLSF algorithm that has much
+  better memory fragmentation behaviour. According
+  to [http://www.gii.upv.es/tlsf/](http://www.gii.upv.es/tlsf/) the maximum
+  fragmentation measured is lower than 25%. As a nice bonus ``alloc`` and
+  ``dealloc`` became O(1) operations.
