Ok, maybe I need some vacations...
Last try, from the source "mozilla-release/image/src/RasterImage.cpp":

RasterImage::DecodePool::DecodePool()
 : mThreadPoolMutex("Thread Pool")
{
  if (gMultithreadedDecoding) {
    mThreadPool = do_CreateInstance(NS_THREADPOOL_CONTRACTID);
    if (mThreadPool) {
      mThreadPool->SetName(NS_LITERAL_CSTRING("ImageDecoder"));
      uint32_t limit;
      if (gDecodingThreadLimit <= 0) {
        limit = std::max(PR_GetNumberOfProcessors(), 2) - 1;
      } else {
        limit = static_cast<uint32_t>(gDecodingThreadLimit);
      }

      mThreadPool->SetThreadLimit(limit);
      mThreadPool->SetIdleThreadLimit(limit);

      nsCOMPtr<nsIObserverService> obsSvc = mozilla::services::GetObserverService();
      if (obsSvc) {
        obsSvc->AddObserver(this, "xpcom-shutdown-threads", false);
      }
    }
  }
}
