This patch makes the "/ID" field optional.
If the environment variable GS_GENERATE_UUIDS is set to "0" or "no", it will
not write out the "/ID" field (if that's permissible).
Upstream does not want to do this.

commit/build-aux/cuirass?id=98a6642298be6663b9d318b7dea46d1dba275839'>cuirass: Fork inferior processes before creating threads....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'.

| 2022-05-20 | cuirass: Close each inferior upon completion....* build-aux/cuirass/evaluate.scm <top level>: Add 'close-inferior' call.

system.
