I only get this error when the package is emerged with SCHED_IDLE scheduling policy, i.e. via 
PORTAGE_IONICE_COMMAND="chrt -i -p 0 \${PID}"
commenting that out / creating a seperate package.env fixes it - looks to me like the sched_batch test fails if it's not started as SCHED_RR

tested with both 3.3.15-r1 and 3.3.16-r2

Update summary. [something] is used when something refers to an overlay

Is there any way to restrict PORTAGE_SCHEDULING_POLICY on a per-ebuild basis?  Even if it's just a bail-out in pkg_setup etc?
