B18 installed - it includes a fix for B3

[Rob Hartill <ha...@ooo.lanl.gov>]

I just put the redirect patch fix onto hyperreal, and
I see that it fixes "B3", but in a much safer way. B3 just
removed the kill_children line - which could leave a script
which redirected and produced a body running 'forever'.

Here's a question I don't think we've discussed so far,
while we're working on a new release, do we give full
permission to NCSA et-al to take our code for themselves ?
Do we need a temporary (c)  ?
