In reality I just renamed an existing builder that was running inside
a VM on Mac Mini.

I have probably configured one hour delay before the builds start to
avoid building sequential commits too many times.
I don't have any notifications configured when failures happen, but I
happened to be fiddling with the hardware around that time, so I
noticed the issue before all other builds were even finished.

(Btw, the builds inside the virtual machine on M1 are ten times faster
than on RPi 4 using a fast external SSD. OpenBSD seems to be the
slowest beast for compiling TeX Live by a huge margin: up to 3-5 times
slower than Debian Linux when it's running on the same hardware with
the same amount of allocated resources. Admittedly it's all running
inside a VM that might not be fully optimized for OpenBSD, but still
...)
