 /* This returns a pointer to the memory area associated with the

-   "process" callback. For an output port, it will be a memory area
+   specified port. For an output port, it will be a memory area
    that can be written to; for an input port, it will be an area
    containing the data from the port's connection(s), or
    zero-filled. if there are multiple inbound connections, the data
    will be mixed appropriately.  
 
-   You may not cache the values returned across process() callbacks.
-   There is no guarantee that the values will not change from

+   You may cache the value returned, but only between calls to

+   either never cache the return value or ensure you have
+   a "blocksize" callback and be sure to invalidate the cached
