I've updated php yesterday and I noticed that cuirass is now busy building dependents on aarch64. Looking at the log of some of them, it seems that the workers are independently building the same php derivation, and not the dependents, at the same time. This is extremely wasteful as php is very long to build (and might even eventually fail). here is an example: https://ci.guix.gnu.org/build/287478/details and https://ci.guix.gnu.org/build/287476/details are being built at the same time, and the logs currently show they are both running the test phase of the php package. Shouldn't cuirass first schedule builds for dependencies before it builds dependents?
