Paket confusing parallel package downloads with each other

Description

Lately I often run into an issue where Paket seems to confuse parallel downloads with each other, and putting the content of one nupkg into the file name of another package.

For example, after trying to use Accord, within the AppData/Local/NuGet/Cache folder, the file Accord.Extensions.Core.3.0.1.nupkg actually contains the data that it should have written to another file name Accord.Extensions.Math.3.0.1.nupkg.

This does not happen when I use e.g. the NuGet Package Explorer to download the same package from the same feed (otherwise I’d have suspected our proxy server to mess things up).

Am I the only one seeing this form time to time?

Repro steps

1. clean caches
2. Try to restore the following lock file:

GROUP Benchmark
FRAMEWORK: NET45
NUGET
  remote: http://www.nuget.org/api/v2
    Accord (3.3)
    Accord.Extensions.Core (3.0.1)
      Accord (>= 3.0.2)
    Accord.Extensions.Math (3.0.1)
      Accord.Extensions.Core (>= 3.0.1)
      Accord.Statistics (>= 3.0.2)
      DotImaging.Primitives2D (>= 2.5.3)
    Accord.Math (3.3)
      Accord (>= 3.3)
    Accord.Statistics (3.3)
      Accord (>= 3.3)
      Accord.Math (>= 3.3)
    DotImaging.Primitives2D (4.8.3)

and dependencies file:

group Benchmark
    source http://www.nuget.org/api/v2
    framework: net45
	nuget Accord.Math
	nuget Accord.Extensions.Math

Expected behavior

Download Accord.Extensions.Core.3.0.1 into the Accord.Extensions.Core.3.0.1.nupkg cache file, and Accord.Extensions.Math.3.0.1 into the Accord.Extensions.Math.3.0.1.nupkg cache file.

Actual behavior

Downloads Accord.Extensions.Math.3.0.1 into the Accord.Extensions.Core.3.0.1.nupkg cache file.

What if you switch to https?
