Makes sense. I cannot think of a use-case now, but I thought maybe there
would be a reason to catch all UnknownErrno## classes without catching all
py.error.Error subclasses. If you do catch all Error classes you would
have to evaluate the e.__class__.__name__ to see if it begins with
"UnknownErrno".

Don't mind me, it's probably just my tendency to overdesign :-)
