Occasionally (2 or 3 times a day) my program crashes with the following:

>>> %Run -c $EDITOR_CONTENT

MPY: soft reboot
malloc self
set fb pointers
m_new_class(ST7701...
launch core1
launched core1
core1 returned

[[[[ Program output ]]]]

Traceback (most recent call last):
  File "<stdin>", line 265, in <module>
  File "touch.py", line 66, in poll
  File "touch.py", line 77, in _handle_touch
OSError: [Errno 5] EIO

The call in line 265 in my program is merely a call to touch.poll().
The line 77 in _handle_touch is dealing with i2c - I have no additional i2c devices attached to the Presto

It's not reproducible in that I don't know what to do to cause it, but if I poke at the screen for long enough, it will happen!
