Thanks very much.  I really appreciate this.

I've given up on vfork, btw.  When I first wrote vfork many years ago
there were obvious performance improvements.  However, with all of the
cruft I've had to add over the years to make it run exactly right, my
recent timings show that it is actually now slightly *slower* than fork.
So, since most of my headaches with the tty code are with vfork, I'm
just disabling it -- at least for now.  I think it's possible to do what
needs to be done more efficiently but I am not going to waste time on YA
destabilizing DLL change.

So, bye bye vfork.
