I don't think that three is a priority assigned to sigals based on the
user, but I might be wrong. If the process is in the middle of a
system call though, I think it runs in kernel space. This means that
there are no signals it can't ignore... I know this is the case for
kernel threads (a signal is just a flag that gets set, and the thread
has to be nice about listening).
