Since you're being nice and helpful I figured I'll try testing TCP-AO
with debug options enabled :) (kernel/configs/debug.config and
kernel/configs/x86_debug.config included), that slows things down 
and causes a bit of flakiness in unsigned-md5-* tests:

This has links to outputs:

If it's a timing thing - FWIW we started exporting
KSFT_MACHINE_SLOW=yes on the slow runners.
