This code perhaps should call syslog() which has a chance of logging
an error, but in real life it is difficult to get sigaction() to fail
if you pass it correct arguments.

I admit in my own code I try to do something sensible if sigaction()
fails and I'm sure if you write a clean fix someone will commit
it, given the NetBSD project's liking for doing things The Right
Way. :-)
