  Log Message:
  -----------
  remove incorrect comment

- both Thread.remove and thread_suspendAll synchronize on slock
  so a double removal isn't possible
- we still set isRunning to false b/c some functions must not be called
  on a stopped thread, e.g. setPriority

  Log Message:
  -----------
  fix double removal of thread

- happens when removing a running thread (thread_detachInstance) that
  gets removed again at the end of thread_entryPoint
- fixed by setting .prev/.next to null on removal and checking for that
- requires the obvious care when removing threads while looping over the list
- also helps the GC a bit to collect dead Thread objects
