I am trying to fix these issues for the next version, and do b) in the
cases you mention.  My thought before was to check for various
specific errors (as in various kinds of IOError), keep going if the
error was recognized as one it made sense to keep going from, and
abort otherwise.

    But it seems hard to recognize all these errors, which may
different from system to system, so now I think it makes more sense to
do it the opposite way, and keep going unless an error is recognized
as one we should stop because of.
