I think the API is ok. The 'part' argument is used for
accumulating the result. But there's a bug in 2.0-beta3:
the size of the partial result is not taken into account.

Fix for buffer.c, buf_meth_receive():

-     } else err = recvraw(buf, (size_t) lua_tonumber(L, 2), &b);
+     } else err = recvraw(buf, (size_t) lua_tonumber(L, 2) - size, &b);
