That should be ok as well.  There is an overflow guard in the api
entry point so that should guard against overflows from user space.

On the network end I miscalculated a little.  The key is actually made up
of user_key (1 short) + 2 * key_vector (3 shorts) for a total of 7*MAX_USHORT;
however, that still will not overflow 32 bits.
