I think everything, but especially the network, is just slow on this builder. (Compare #37322, #35692, #35498, #34837.)

(CC @toothrot @cagedmantis @andybons @dmitshur, since they may suggest a builder-based solution to this cluster of flakes.)

The apparent deadlock in net suggests a possible connection to #34837. (Perhaps a platform bug on Corellium?)
