Fix previous commit. The standards specifically say: "The structure
sigaction, used to describe an action to be taken, is defined in the
header <signal.h> to include at least the following members:"
^^^^^^^^
A sigaction defined on stack with essentially random contents may have
just about anything underneath fields that the program doesn't know about.
It is not safe to delete the bzero.
