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 &lt;top level&gt;: Call 'open-inferior'
before 'n-par-for-each'.
