[logback-user] Logback suddenly stopped logging

[Joern Huxhorn]

OMG, I wasn't aware of such an issue with IOException.

I guess that my code is suffering from the same issue. I've just implemented a small utility class for later use.
http://github.com/huxi/sulky/blob/master/sulky-io/src/main/java/de/huxhorn/sulky/io/ThreadInterruptionSafeguard.java

Please give the code a quick look and tell me if I forgot something or missed some point.

Thanks,
Joern.
