The default action for a given signal is architecture dependent. Since
we're discussing linux here though, here's relevant information on
SIGKILL from the signal(7) manpage:
The signals SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
The POSIX.1 standard defines default actions for SIGTERM and SIGKILL to
be process termination, so by default, SIGKILL will try to kill the
current process immediately. Sometimes, the process will not
immediately be terminated, like when it is performing disk I/O; this
rarely happens in practice.
