+2.5 Reusable Call Plans
+=======================
+
+When the same signature is called many times - as language bindings
+typically do - you can build a “call plan” once and reuse it, so that
+each call avoids the work ‘ffi_call’ would otherwise repeat on every
+invocation.  A plan is an opaque, caller-owned object built from a
+prepared ‘ffi_cif’.
+
+ -- Function: ffi_call_plan * ffi_call_plan_alloc (ffi_cif *CIF)
+     Builds and returns a reusable plan for the signature described by
+     CIF, which must already have been prepared with ‘ffi_prep_cif’.
+     The plan does not copy CIF; CIF must remain valid for as long as
+     the plan is used.
+
+     Returns ‘NULL’ only when memory cannot be allocated.  A signature
+     for which no accelerated path exists is still valid: the returned
+     plan simply falls back to ‘ffi_call’ when it is invoked.
+
+ -- Function: void ffi_call_plan_invoke (ffi_call_plan *PLAN, void *FN,
+          void *RVALUE, void **AVALUES)
+     Calls FN using PLAN.  The FN, RVALUE, and AVALUES arguments have
+     exactly the same meaning as for ‘ffi_call’ (*note The Basics::),
+     including the rule that integral return values narrower than a
+     register are widened to ‘ffi_arg’.
+
+     A plan is immutable once built, so a single plan may be invoked
+     concurrently from multiple threads without additional locking.
+
+ -- Function: void ffi_call_plan_free (ffi_call_plan *PLAN)
+     Releases a plan returned by ‘ffi_call_plan_alloc’.  Passing ‘NULL’
+     is harmless.  The ‘ffi_cif’ the plan was built from is not
+     affected.
