We intentionally removed the daemonization support that used to
be there; see commit f7ea6beaf4ca02b8e6dc576255e35a5b86035cb9.
One of the things it did was exactly this. I'm a bit disinclined
to put that back.
If this is, as it sounds to be, a Solaris shell bug, doesn't it
affect other daemons too?
