+memcached_get_memory_allocators_context() returns the void * that was
+passed in during the call to memcached_set_memory_allocators().
+
+The first argument to the memory allocator functions is a pointer to a
+memcached structure, the is passed as const and you will need to clone
+it in order to make use of any operation which would modify it.
+
+=head1 NOTES
+
+In version 0.38 all functions were modified to have a context void pointer
+passed to them. This was so that customer allocators could have their
+own space for memory.
