As background information from Windows testings:
- the debug port event is closed upon thread regular exit.
- results are however inconsistent across Windows versions for forced
  termination (through TerminateThread and equiv).
- this is moreover crippled by most of the 32bit implementation on Windows
  (except Win8) which don't enforce the close on exit flag for wow64 debuggee:s
  (they enforce it for 64bit though)
- but, in the cases where the debuggee terminates, the debug port is
  always closed *after* the debuggee process termination.

So I adapted the tests to conform to "debug port is closed" when handling
the thread termination. Some tests had to be moved *after* debuggee
termination to ensure success.
