ARM machines and other weakly-ordered architectures have been suffering
for a long time from hangs in qemu-img and qemu-io. For QEMU binaries
these are mitigated by the timers that sooner or later fire in the main
loop, but these will not happen for the tools and probably not with I/O

on the main AioContext. If I add assertions for this however I see a
