I agree that this should be fixed; I'm not sure I like the proposed fixed, though. It discards the exception and keeps running.

What it (IMO) should do instead is abort, then return the data on the next invocation. Of course, this may have problems in itself, since the file descriptor might not report read-ready when passed to select or poll, even though data are available.

Please discuss this on python-dev (and elsewhere), and report what recommendations people made.
