Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Following the ‘core-updates’ merge, evaluations started by ‘cuirass
register’ seem to never complete.
The log shows things like “evaluating spec 'shepherd'” but there’s never
an indication of completion of failure.
The ‘cuirass register’ process spins at 100% after the ‘cuirass
evaluate’ process has failed, as if ‘evaluate’ in (cuirass base) did not
react properly to the end-of-file from the pipe:

This looked like a déja vu; turns out we were using Fibers 1.0.0…
