+
+    shadow: Fix can not print full login timeout message
+    
+    Login timed out message prints only first few bytes when write is immediately followed by exit.
+    Calling exit from new handler provides enough time to display full message.
+
+Upstream-Status: Accepted [https://github.com/shadow-maint/shadow/commit/670cae834827a8f794e6f7464fa57790d911b63c]
