Test fails to terminate: ttg/test/core-unittests-ttg-parsec/run-np-2

[G-Ragghianti]

Most of the time, the test ttg/test/core-unittests-ttg-parsec/run-np-2 fails to terminate within the 1500s timeout. This test normally takes only a few seconds. I have attempted to reproduce the correct passing test that the current TTG CI has, but I've been unable to reproduce a successful test using a docker image that is very close to the Github ubuntu runner image. My tester is in my docker-based test reproducer repo at https://github.com/G-Ragghianti/docker/tree/main/ttg.tesse

To reproduce:

$ git clone https://github.com/G-Ragghianti/docker
$ cd docker/ttg.tesse
$ docker build .
