VS2013 permanent CPU usage even though in idle mode

Edit 2: Possible bug regression in Updates 3 & 4.

Edit 1: The bug was fixed in VS2013 Update 2.

One can disable git plug-in from Visual Studio 2013 in this way:

Tools->Options

Source Control: set Current source control plug-in to None

Use other git clients to manage your repositories.

For me (VS 2013 update 4) the solution was to disable Browser Link as specified here:

The CPU slowed down right away from 25 % to 1 %.
