Yeah, I'd already put that back but actually, now that I think of it,
keeping this open may actually be what we want to do.  Keeping it open
will ensure that the shared memory will be around so the process will
essentially stay around as long as you have the shared memory open...
sort of.

If I understand the way this works, there will normally only be one of
these open at any time, anyway, so resource usage is not that great.

I don't know if there are other issues with this or not, though.
