While it is true that you can call as many times as you want the method, it wont actually start processing until the previous one is over. I decided to decompile the dll to see what was up behind the curtain. The function EslClient.CreatePackage(DocumentPackage) calls EslClient.UploadDocument() which calls PackageService.UploadDocument. Here is the code for the latter

internal Silanis.ESL.SDK.Document UploadDocument(DocumentPackage package, string fileName, byte[] fileBytes, Silanis.ESL.SDK.Document document)
    {
      lock (PackageService.syncLock)
      {
        string local_0 = this.template.UrlFor(UrlTemplate.DOCUMENT_PATH).Replace("{packageId}", package.Id.Id).Build();
        Package local_1 = new DocumentPackageConverter(package).ToAPIPackage();
        Silanis.ESL.API.Document local_2 = new DocumentConverter(document).ToAPIDocument(local_1);
        try
        {
          string local_3 = JsonConvert.SerializeObject((object) local_2, this.settings);
          byte[] local_4 = Converter.ToBytes(local_3);
          string local_5 = this.GenerateBoundary();
          byte[] local_6 = this.CreateMultipartContent(fileName, fileBytes, local_4, local_5);
          return new DocumentConverter(JsonConvert.DeserializeObject(this.restClient.PostMultipartFile(local_0, local_6, local_5, local_3)), local_1).ToSDKDocument();
        }
        catch (EslServerException exception_0)
        {
          throw new EslServerException("Could not upload document to package. Exception: " + exception_0.Message, exception_0.ServerError, exception_0);
        }
        catch (Exception exception_1)
        {
          throw new EslException("Could not upload document to package. Exception: " + exception_1.Message, exception_1);
        }
      }
    }

Is there a way around the lock with the SDK or do I need to use the REST API?
