Title:
  running large tests via nunit-console-x86.exe results in
  OutOfMemoryException

Status in NUnit V2 Test Framework:
  Triaged

Bug description:
  Hi,

  when we're running large tests with many assemblies we get an
  OutOfMemoryException. Maybe there is an issue with the dispose of the
  runners. We currently avoid this problem with a temporarily fix. As
  you can see below, we dispose every runner after its AddResult is
  complete.

  src/ClientUtilities/util/AggregatingTestRunner.cs
  ...
  else
  {
      foreach (TestRunner runner in runners)
          if (filter.Pass(runner.Test))
          {
              try { result.AddResult(runner.Run(this, filter, tracing, logLevel)); }
              finally {  runner.Dispose(); }
          }
  }
  ...
  public void Dispose()
  {
      foreach (TestRunner runner in runners)
          if (runner != null)
          {
              //runner.Dispose();
          }
  }

  We're not sure if this could cause any side effects, but for now it
  helps us through. We can reconstruct this problem with a simple dummy
  test where memory is allocated by a big static array. Also get the
  OutOfMemoryException with a heap of 1.457.708K, with the fix the test
  is running through with a heap of 450.944K.

  We're running NUnit with the pre 2.6.2 version, but the problem also occurs in release 2.6.1.
  [Runtime Environment]
  [OS Version: Microsoft Windows NT 5.1.2600 Service Pack 3]
  [CLR Version: 4.0.30319.269 ( Net 4.0 )]

  Tried also some different parameters, but running with default
  settings for now.

  Thanks in advance.
