 ### Memory ownership
 
 A task owns all memory it can *safely* reach through local variables,
-shared or unique boxes, and/or references. Sharing memory between tasks can
-only be accomplished using *unsafe* constructs, such as raw pointer
-operations or calling C code.
+as well as managed, owning and borrowed pointers.
 
-When a task sends a value that has the `send` trait over a channel, it
-loses ownership of the value sent and can no longer refer to it. This is
-statically guaranteed by the combined use of "move semantics" and the
-compiler-checked _meaning_ of the `send` trait: it is only instantiated
-for (transitively) unique kinds of data constructor and pointers, never shared
-pointers.
+When a task sends a value that has the `Send` trait to another task,

+This is statically guaranteed by the combined use of "move semantics",
+and the compiler-checked _meaning_ of the `Send` trait:

 When a stack frame is exited, its local allocations are all released, and its
 references to boxes (both shared and owned) are dropped.
