Why do we need to spam the logs with such information?

SIGXCPU is only ever sent by this code. If there is a signal handler
in the application it's easy to debug. If not it's even easier, the
thing will simply be killed and you get the reason printed.

For the SIGKILL case there only a limited number of reasons why a
SIGKILL is sent. So no, I rather commit a patch which removes that
ugly printk which is already there instead of adding more of them.
