In my tests, it fails with a different error. This error is also present in
this log:

This also leaves running mysqld and memcached processes.

These tests should be fixed (or disabled) to fix the FTBFS.

It seems ruby-em-synchrony is only used as a build-dependency for
ruby-faraday. That build-dependency can be removed by disabling the
em-synchrony tests (and updating the coverage settings). Maybe that should be
done, to allow em-synchrony to be removed from bullseye?

Cheers,
