Problem
When a signal is sent to YaST (e.g., when the parent terminal is killed), YaST tries writing a message to the standard error output. But stderr can be closed at that time, making YaST to raise an exception.
Solution
Avoid IO error by doing "exception swallowing" for Errno::EIO while writing to stderr.
See also yast/yast-control-center#51.
Testing
Manually tested.
