Because sometimes a program wants to terminate. And it is perfectly legal
for a programmer who needs to terminate his program as quickly as possible
to do this:

char *j=NULL;
signal(SIGSEGV, SIG_DFL);
*j++;

This is a perfectly sensible thing for a program to do with well-defined
semantics. If a program wants to create a child every minute like this and
kill it, that's perfectly fine. We should be able to do that in the default
configuration without a sysadmin complaining that we're DoSing his syslogs.
