Parallel permission insert requests grant the permission for only one of the two users

[GoogleCodeExporter]

Sorry if I post this problem in a wrong place, should it be a service issue?

I know the Drive SDK doesn't support batch requests yet, so I'm trying to use 
parallel requests to achieve the functionality but it doesn't seen to work 
properly.

What steps will reproduce the problem?
1.Upload a small txt file with DriveService.Files.Insert 
2.Create 2 parallel requests to add permissions 
(DriveService.Permissions.Insert) for two different users, I'm getting success 
responses for both requests
3.Delegate the two users' account and use DriveService.Files.Get to get the file

What is the expected output? What do you see instead?
I expected the two users' account can access the uploaded file, but I'm getting 
404 error for one of them. I suppose only one of the request is effective.

Hi,
I think you should take a look in the Google Drive support page
https://developers.google.com/drive/support
It looks like they offer you to open a new issue in StackOverflow.

I'm closing this issue because isn't relevant to this library,
feel free to reopen if you feel that it should be here.

Thanks!
