hangfire.entityframeworkcore这个库因为System.Threading.Timer未停止也未释放而导致的性能问题

如题
https://github.com/sergezhigunov/Hangfire.EntityFrameworkCore/issues/32

public class Worker : IBackgroundProcess
{public void Execute(BackgroundProcessContext context){using (var fetchedJob = connection.FetchNextJob(_queues.ToArray(), context.StoppingToken)){...fetchedJob.RemoveFromQueue();// 它会设置EFCoreFetchedJob._completed=true，进而导致后续的_timer.Dispose()未执行...}}
}

internal sealed class EFCoreFetchedJob : IFetchedJob
{private bool _completed;public void RemoveFromQueue(){lock (_lock){_storage.UseContext(context =>{context.Remove(_queuedJob);try{context.SaveChanges();}catch (DbUpdateConcurrencyException){// Someone else already has removed item, database wins}});_completed = true;//这里在Dispose前就执行了}}public void Dispose(){Dispose(true);GC.SuppressFinalize(this);}private void Dispose(bool disposing){if (!_disposed){if (disposing && !_completed)//因为_completed=true，所以_timer.Dispose()不执行{_timer.Dispose();Requeue();}_disposed = true;}}
}
