This actually fixes the problem, however I was running a development branch without it and mistakenly thought it wasn't fixed. Fixes issue #10010, and #9654: 100% CPU usage caused by an asterisk console losing it's controlling terminal. ........ ................ git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@72384 65c4cc65-6c06-0410-ace0-fbb531ad65f3
