This should only occur if the first signal didn't get through to the whole
process group.  If stapio received the first signal, it should shut down in
a timely manner, and let stap shut down cleanly too within a few seconds.

The second signal should only be necessary if something broke with handling the
first one - it's sort of a user-level patience timeout measure that should not be
necessary for mechanical use.
