Okay, I understand now.  But still, TclAE should have a SafeInit which 
returns TCL_ERROR.  That way you are really telling a safe interpreter 
that you are unsafe...

Yeah, this is something the Finder does.  But I don't think that this is 
what assigns the PSN, it is just passing it to the process.  So what you 
would really need to do is get Tcl to register with the WindowServer.  
Somebody sent some code to do this - I think to the list - but I can't 
find it now...
