[PATCH] uml: fix SIGWINCH handler race while waiting for signals.
If a SIGWINCH comes in, while winch_thread() isn't waiting in wait(), winch_thread could miss signals. It isn't very probable, that anyone will see this causing trouble, as it would need a very special timing, that a missed SIGWINCH results in a wrong window size. So, this is a minor problem. But why not fix, as it can be done so easy?
