Disable signal handling (temporarily for fineweb)
Now Kube shows the reason "Error" (so not "OOM") but thanks to logging I managed to see that the main process did receive a SIGTERM.

Temporarily disable some signal handling in case they prevent some logs from the children processes to appear, or if it prevents Kube from detecting the OOM.
