async @napi-rs/canvas crashes under load

[7f8ddd]

How can we reproduce the crash?

bun i @napi-rs/canvas

import { createCanvas } from "@napi-rs/canvas";

async function generate() {
  const canvas = createCanvas(400, 200);
  const ctx = canvas.getContext("2d");

  ctx.fillStyle = "#FFFFFF";
  ctx.fillRect(0, 0, canvas.width, canvas.height);

  const encoded = await canvas.encode("webp");

  return `data:image/webp;base64,${encoded.toString("base64")}`;
}

while (true) {
  generate();
}

Relevant log output

This causes things like captcha generation or Discord bot image generation to randomly crash when under load.
By load, I mean around 1000 rq/s or less.

Adding a Bun.sleepSync(1) is how I temporarily resolved the problem.

It may be even less rq/s if the encode takes longer.
