   | And seriously: I just tested it on NetBSD-7.0, and while running the
   | example program, top(1) still showed me 8 zombie processes. So no, it is
   | not fixed.
 
 I'm testing it on 7.0_BETA which is pretty much the same thing, and I
 don't see any more than the occasional zombie - the normal thing you
 expect to see when a process has exited and its parent is temporarily
 busy - and they all go away quite quickly.  I haven't detected more than
 1 existing at any one time.
 
 I am using the standard /bin/sh for this - not the one from current that
 I have been working on.
 
 There are 2 possible differences that I can think of (since I am running
 the script cut & pasted from the PR, unchanged, and I doubt sh put a bug
 back between 7.0_BETA and 7.0) ... perhaps the system architecture is
 important (the PR doesn't say what you're using) - I am testing on amd64.
 
 Or, possibly your /etc/hosts is much bigger (or perhaps smaller?)
 than mine, I have ...

 ps: apologies to all for the mix-up in the PR number when I first asked
 about this...   Mostly for the PRs I have been looking at, and sending
 comments about, I have been pasting the number into the e-mail.  Obviously
 I didn't this time!
