Bug#1297: nohup doesn't seem to work

I think this is a red herring. The signal won't get raised if the handler
is set to SIG_IGN. Moreover, when I run the simple test below, nohup works
correctly. I still suspect something else is getting to the SIGHUP handler
in the test you are running.

	Thanks
