I killed emerge during the merge of sys-apps/portage-2.2_rc74 and sys-apps/gawk-3.1.8, which apparently resulted in some ebuild.sh and ebuild-ipc.py processes being left behind. I noticed this behaviour while trying to unmount /var/tmp/portage. ps aux says: root 23459 0.0 0.1 60608 9960 ?

Add a 40 second timeout in ebuild-ipc.py, so that if an orphan is left for any reason then it will exit with an error message instead of hanging indefinitely: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=12d2ff4f018c826c750896e8085cd53a589a8521
This is fixed in 2.2_rc75 and 2.1.9.
