  - Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
    argument in python 2.5, this broke code that subclassed Popen to include its
    own poll method.  Fixed my moving _deadstate to an _internal_poll method.

  Adds a sanity check to avoid a *very rare* infinite loop due to a corrupt tls
  key list data structure in the thread startup path.

  This change is a companion to r60148 which already successfully dealt with a
  similar issue on thread shutdown.

  In particular this loop has been observed happening from this call path:
   #0  in find_key ()
   #1  in PyThread_set_key_value ()
   #2  in _PyGILState_NoteThreadState ()
   #3  in PyThreadState_New ()
   #4  in t_bootstrap ()
   #5  in pthread_start_thread ()

  I don't know how this happens but it does, *very* rarely.  On more than
  one hardware platform.  I have not been able to reproduce it manually.
  (A flaky mutex implementation on the system in question is one hypothesis).

  As with r60148, the spinning we managed to observe in the wild was due to a
  single list element pointing back upon itself.

  Issue #1481296: (again!) Make conversion of a float NaN to an int or
  long raise ValueError instead of returning 0.  Also, change the error
  message for conversion of an infinity to an integer, replacing 'long' by
  'integer', so that it's appropriate for both long(float('inf')) and
  int(float('inf')).
