  // logging task, which then gets called synchronously before the callback
  // actually yields to the calling thread. This is in contrast to what the
  // logging would look like if the call was coming from within Deno itself,
  // and may lead users to unknowingly run heavy asynchronous tasks from thread
  // safe callbacks synchronously.
  // The fix would be to make sure microtasks are only run after the event loop
  // middleware that polls them has completed its work. This just does not seem
  // to work properly with Linux release builds.
