Thanks for the test run, and sorry for the churn.  It looks like these
are all failing with "error: no fdcache hits" because every addition to
the fdcache results in "fdcache emergency flush for filling tmpdir".  I
see that run-debuginfod-fd-prefetch-caches.sh has a workaround for this
which I'll copy.

Thanks,
Omar
