In the mean time I did a quick fix on my system in config.scm:
```
(use-modules (gnu)
(gnu packages ci) (guix packages) (guix utils))
(define-public cuirass/queue-1
(package/inherit cuirass
(name "cuirass-queue-1")
(arguments
(substitute-keyword-arguments (package-arguments cuirass)
((#:phases phases)
`(modify-phases ,phases
(add-after 'disable-repo-tests 'set-queue-size
(lambda _
(substitute* "src/cuirass/database.scm"
(("queue-size 100") "queue-size 1"))
#t))))))))
```
Plus (cuirass cuirass/queue-1)
in the cuirass-configuration. So no need from my side to hurry anmyore :)
