I think there are 2 problem with this approach:
1) That still doesn't solve the problem of the Octave quit function  
and the signal handlers calling exit().  I suppose I could replace all  
the Octave signal handlers with my own, but that seems like just  
asking for trouble and would still have the problem with the Octave  
quit function.
2) How do you force octave_parse () to return something other than  
zero to make it exit the main_loop function?  I tried looking through  
parse.cc, but can't understand exactly what is going on in the  
octave_parse function (#defined as the yyparse function) and what  
exact condition will cause it to return a non-zero value.
