Thanks for the test case.

I've checked in a fix but it is pretty ugly.  I don't know of any other
way to accomplish what is required for setsid other than to do a fork()
when setsid is called in a "vfork" condition.  So, that's what I did.

I noticed a few other bugs with vfork and fixed them.

I also implemented getsid().  I can't believe that it has been missing
all of this time.

Your test case seems happier (if slower) now.

I'm rebuilding YA snapshot.
