When you hit a brekpoint in gdb non-stop mode, if you click continue in the
UI the debugger was killed if the current thread is not the one being
stopped. This is anoying as gdb does not change current thread
automatically. The fix shows the error but does not kill the inferior.
Fixed style issues again.
