Steps to reproduce

• Setup Ubuntu 14.04 instance to test on
• Install latest dotnet runtime
• Create new project as root
• Execute dotnet restore
• Login as another user
• Create new project as other user
• Attempt to execute dotnet restore
• You will see a permission error, attempting to access /tmp/NuGetScratch/lock

Expected behavior

dotnet restore should work as expected and my project's dependencies should be restored.

Actual behavior

dotnet restore attempts to re-use the /tmp/NuGetScratch/lock causing a permissions error and failing out.
