Intermittent build issues

I occasionally see failures in unit tests when NUnit's internal communications fail, which then go away when I retry the build. If you see them, just re-try

One looks like this

System.Runtime.Serialization.SerializationException : The object with ID 2 implements the IObjectReference interface for which all dependencies cannot be resolved. The likely cause is two instances of IObjectReference that have a mutual dependency on each other.
--SerializationException

Another looks like

NUnit.Engine.NUnitEngineUnloadException : Multiple exceptions encountered. Retrieve AggregatedExceptions property for more information
  ----> System.Runtime.Remoting.RemotingException : Tcp transport error.
  ----> System.Runtime.Remoting.RemotingException : Tcp transport error.

Also, occasionally, something looking like a race in the depths of the FSharpLint MSBuild task

I've seen reports of what looks like FSharpLint issue #250 when building:-

 error : Exception: Lint failed while analysing path-to\AltCover.Recorder.fsproj.
 error : Failed with: error parsing ProjectCrackerTool output, stdoutput was:
 error :
 error :
 error :
 error : stderr was:
 error :
 error : Process is terminated due to StackOverflowException.

though none of the machines I've used have shown this behaviour, so I can't hazard a guess at what in the environment might be causing it. I'm sure that project would like the issue fixing, if you can repro it.
