The messages are sent for the process handle itself. The handling of dispose in
ProcessWaitHandle seems seriously screwed up:
- we keep a separate 'dispose' field, then call the superclass Dispose ()
method,
  which checks it own 'dispose' field, which is also false, so the superclass
  Dispose () is executed as well.
- in 1.0, WaitHandle.Dispose () closes the handle again, so the same handle is 
closed twice, for some reason, this does not seem to cause a problem.
- in 2.0, we wrap the handle value in a SafeWaitHandle, which we also close in
  WaitHandle.Dispose (), so the handle is again closed twice, this causes the
  wapi_unref () messages.
