Was wondering if anyone out there has had a problem with application
light weight processes being hung at exit time if "bindkey" was used to
bind a piece of NeWS code to a particular key?  We are experiencing the
following:  an application uses the bindkey utility.  Seems to work
just fine;  The code, bound to the key in question, runs as expected
when the key is pressed.  Then, when trying to exit, the lwp who called
bindkey is hung until the key is pressed.  If the key is pressed, the
lwp exits normally.

Looking at the UI.ps code, it appears that the lwp, created to be interested
in the key, is created with a different lwp group:

        /bound_keys_proc {
            newprocessgroup
            createevent dup begin
            /Name bound_keys def
            /Action /DownTransition def
            /Exclusivity true def
            /Priority 3 def
            end expressinterest
            { awaitevent } loop
        } fork def

What kills this guy when his creator is gone?  Is that what causes the
creator to be hung?

Hope this isn't too much old hat, being a NeWS 1.1 problem, and all.

Thanks (wishful thinking)
