This breaks oe-selftest:

https://autobuilder.yocto.io/builders/nightly-oe-selftest/builds/248/steps/Running%20oe-selftest/logs/stdio

Perhaps not all the failures but certainly:
wic.Wic.test_rawcopy_plugin_qemu
wic.Wic.test_qemu_efi
wic.Wic.test_qemu

We see intermittent failures on these tests anyway and I think you're
onto the right track with a potential fix though.

Cheers,

Richard
