That's a fact of *NIX life I am afraid: KILL is unstoppable (ignore), as is
SIGSTOP - they provide the user/admin with a "surefire way of either killing
or stopping a process" --Stevens.
And, as catching these would also enable you to ignore them, you cannot do
that either!
I did not read the whole thread, but if you are doing more than just
handling error conditions/froceful termination from the kernel, you should
be aware that signals hanve slightly different behaviors across the *NIX
spectrum. This is particularly relevant if you take to blocking them, or if
you want them to interrupt/restart the so called "slow system calls".
