Error type mismatch issue in reactor handle_error

[sancar]

handle_error is assuming that all errors it gets are IOError.
There is a type check needed in handle_error
There are user reports than it can get other errors there like following:

'Traceback (most recent call last):

 if error.errno != errno.EAGAIN and error.errno != errno.EDEADLK:
