Exception after adding two devices

[bustawin]

I added a device, and once it started I added another. The result was the following exception:

Traceback (most recent call last):
  File "erasetor.py", line 373, in <module>
    ErasetorServer()
  File "erasetor.py", line 77, in __init__
    wrapper(self.start)
  File "/usr/lib/python2.7/curses/wrapper.py", line 43, in wrapper
    return func(stdscr, *args, **kwds)
  File "erasetor.py", line 98, in start
    self.start_erasetor_process()
  File "erasetor.py", line 92, in start_erasetor_process
    main_menu.display()
  File "erasetor.py", line 138, in display
    devices = self.process.get_list()
  File "erasetor.py", line 364, in get_list
    for device in self.devices:
RuntimeError: dictionary changed size during iteration

Note that not always happens, and I couldn't reproduce the error again.

This bug should be fixed with this commit. When the dictionary size is changed raises an error. Now when the error is raised same function will be called to get a a complete list again.
