Slow compared to what?

You mean all I would have to do is have a preemptive OS and my programs 
would automatically be more portable? I guess that would also take care 
of all of the other system specific function calls like Quickdraw, the 
menu manager, etc.  The only thing that is halfway portable is ANSI-C, 
every OS has it's own API that isn't portable.  A portable program 
wouldn't be able to take advantage of all the OS specific features.  
If I were porting a program the least of my worries would be WNE().
