We now print less kind information in error messages

It prints the getSystemID otuput, which varies from system to system.

It relies on old signal-handling behaviour

It relies on looking at unix group data, which isn't sufficiently

It relies on an order of execution that isn't guaranteed.

It was an interactive test

It doesn't look like we've ever run it, I'm not sure exactly what it
was supposed to test, and it looks like it relies on a particular form
of "ps" output.
