[windows] Flaky testcase in Appveyor CI #2835
Description
Description
I see that one case related to content store failed because the test binary removes the file which hold by containerd process.

The case will close the grpc stream. However, the content service doesn't close file descriptor synchronously. Before the file is closed, the cleanup will call Abort to remove the file. But it failed in windows. I am not sure that it is related to windows kernel. I can not reproduce The process cannot access the file because it is being used by another process. in linux kernel.
