Subject: bitbake: bitbake-worker: exit normally when SIGHUP
X-Git-Tag: rev_ivi_2015_02_04~811
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7eb33cdb4d4f3daf7de3c018bbad9c39eccaa597;p=scm%2Fbb%2Ftizen-distro.git

bitbake: bitbake-worker: exit normally when SIGHUP

Fixed:
1) Run "bitbake recipe" in the terminal
2) Close the terminal while building
3) $ ps aux | grep bitbake-worker
There will be many processes, and they will keep the resources (e.g.,
memory), and won't exit unless kill or kill -9.
