test scripts hang with high cores count

[emollier]

Greetings,

running the test scripts of simka while stabilizing the upcoming Debian 11, the CI team noted that the program hangs under certain circumstances. Further investigations on my end seemed to reveal that the test was hanging past 9 cores, so as a work around, we are capping the test suite to use no further than 8 cores for the moment. You can refer to Debian bug #986256 for more details.

Do you think this would be an issue within simka, or more something intrinsic to the test data topology?

Kind Regards, Étienne.
