From 97dd057702d167559cdaee86eb0b1a455d925168 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fixed issues when running mtr with --valgrind

- Note that some issues was also fixed in 10.2 and 10.4. I also fixed them
  here to be able to continue with making 10.5 valgrind safe again
- Disable connection threads warnings when doing shutdown
