+ * \param memory_size the maximum number of bytes a linear memory can grow to.

+ * \param instances the maximum number of instances that can be created
+ * for a Store. Module instantiation will fail if this limit is exceeded.
+ * This value defaults to 10,000.
+ * \param tables the maximum number of tables that can be created for a Store.
+ * Module instantiation will fail if this limit is exceeded. This value
+ * defaults to 10,000.
+ * \param memories the maximum number of linear memories that can be created
+ * for a Store. Instantiation will fail with an error if this limit is exceeded.

+ * Use any negative value for the parameters that should be kept on
