Because these processes are expected to crash, generating a core dump from them and throwing up a CrashReporter window is less helpful than it is distracting while running many tests at a time. Use the prctl for controlling the core dump-able flag to tell the kernel we don't want core dumps from these processes. Note that because we also build LibTest for Lagom, we have to check for MacOS which doesn't support prctl(PR_SET_DUMPABLE).
