2022-05-26cuirass: Fork inferior processes before creating threads.Ludovic Courtès
Works around <https://issues.guix.gnu.org/55441#12>. Start from commit bd86bbd300474204878e927f6cd3f0defa1662a5, 'open-inferior' uses 'primitive-fork' instead of 'open-pipe*'. As a result, child process could potentially hang before calling 'execl' due to undefined behavior when forking a multi-threaded process. * build-aux/cuirass/evaluate.scm <top level>: Call 'open-inferior' before 'n-par-for-each'.
2022-05-20cuirass: Close each inferior upon completion.Ludovic Courtès
