From: Chris Laplante via bitbake-devel <bitbake-devel at lists.openembedded.org>
Discovered with a recipe under devtool. The ${S}/singletask.lock file (added by
externalsrc.bbclass) was leaked, giving a warning like:
WARNING: <PN>+git999-r0 do_populate_lic: /home/laplante/yocto/sources/poky/bitbake/lib/bb/build.py:582: ResourceWarning: unclosed file <_io.TextIOWrapper name='/home/laplante/yocto/build/workspace/sources/<PN>/singletask.lock' mode='a+' encoding='UTF-8'>
exec_func(task, localdata)

(cherry picked from commit 6beddf6214e22b4002626761031a9e9d34fb04db)
