Comment 19 for bug 785701

I've been pondering this bug all day, I couldn't work out a safe way to test it without causing network errors.

Instead I decided to build a FUSE file-system which can be set to break on certain calls. It will freeze just like this bad network effect and we can test any kind of bad IO handling from there. See https://code.launchpad.net/~doctormo/+junk/gremlinfuse and the accompanying readme. Let me know if you are able to test and what your results are.
